3-9 detailed description the hin232 thru hin241 family of rs-232 transmitters/receivers are powered by a single +5v power supply (except HIN231 and hin239), feature low power consumption, and meet all ela rs-232c and v.28 specifications. the circuit is divided into three sections: the charge pump, transmitter, and receiver. charge pump an equivalent circuit of the charge pump is illustrated in figure 1. the charge pump contains two sections: the voltage doubler and the voltage inverter. each section is driven by a two phase, internally generated clock to generate +10v and - 10v. the nominal clock frequency is 16khz. during phase one of the clock, capacitor c1 is charged to v cc . during phase two, the voltage on c1 is added to v cc , producing a signal across c3 equal to twice v cc . during phase one, c2 is also charged to 2v cc , and then during phase two, it is inverted with respect to ground to produce a signal across c4 equal to -2v cc . the charge pump accepts input voltages up to 5.5v. the output impedance of the voltage doubler section (v+) is approximately 200 ? , and the output impedance of the voltage inverter section (v-) is approximately 450 ? . a typical application uses 1 f capacitors for c1-c4, however, the value is not critical. increasing the values of c1 and c2 will lower the output impedance of the voltage doubler and inverter, increasing the values of the reservoir capacitors, c3 and c4, lowers the ripple on the v+ and v- supplies. during shutdown mode (hin236, 240 and 241), shutdown control line set to logic ?? the charge pump is turned off, v+ is pulled down to v cc , v- is pulled up to gnd, and the supply current is reduced to less than 10 a. the transmitter outputs are disabled and the receiver outputs are placed in the high impedance state. transmitters the transmitters are ttl/cmos compatible inverters which translate the inputs to rs-232 outputs. the input logic threshold is about 26% of v cc , or 1.3v for v cc = 5v. a logic 1 at the input results in a voltage of between -5v and v- at the output, and a logic 0 results in a voltage between +5v and (v+ - 0.6v). each transmitter input has an internal 400k ? pullup resistor so any unused input can be left unconnected and its output remains in its low state. the output voltage swing meets the rs-232c specifications of 5v minimum with the worst case conditions of: all transmitters driving 3k ? minimum load impedance, v cc = 4.5v, and maximum allowable operating temperature. the transmitters have an internally limited output slew rate which is less than 30v/ s. the outputs are short circuit protected and can be shorted to ground indefinitely. the powered down output impedance is a minimum of 300 ? with 2v applied to the outputs and v cc = 0v. receivers the receiver inputs accept up to 30v while presenting the required 3k ? to 7k ? input impedance even if the power is off (v cc = 0v). the receivers have a typical input threshold of 1.3v which is within the 3v limits, known as the transition region, of the rs-232 speci?ations. the receiver output is 0v to v cc . the output will be low whenever the input is greater than 2.4v and high whenever the input is ?ating or driven between +0.8v and -30v. the receivers feature 0.5v hysteresis to improve noise rejection. the receiver enable line en, when set to logic ?? (hin236, 239, 240, and 241) disables the receiver outputs, placing them in the high impedance mode. the receiver outputs are also placed in the high impedance state when in shutdown mode. + - c1 + - c3 + - c2 + - c4 s1 s2 s5 s6 s3 s4 s7 s8 v cc gnd rc oscillator v cc gnd v+ = 2v cc gnd v- = -(v+) c1 + c1- c2 - c2 + voltage inverter voltage doubler figure 1. charge pump t out v- < v tout < v+ 300 ? 400k ? t xin gnd < t xin < v cc v- v+ v cc figure 2. transmitter r out gnd < v rout < v cc 5k ? r xin -30v < r xin < +30v gnd v cc figure 3. receiver HIN231 thru hin241

3-11 applications the hin2xx may be used for all rs-232 data terminal and communication links. it is particularly useful in applications where 12v power supplies are not available for conventional rs-232 interface circuits. the applications presented represent typical interface con?urations. a simple duplex rs-232 port with cts/rts handshaking is illustrated in figure 9. fixed output signals such as dtr (data terminal ready) and dsrs (data signaling rate select) is generated by driving them through a 5k ? resistor connected to v+. in applications requiring four rs-232 inputs and outputs (figure 10), note that each circuit requires two charge pump capacitors (c1 and c2) but can share common reservoir capacitors (c3 and c4). the bene? of sharing common reservoir capacitors is the elimination of two capacitors and the reduction of the charge pump source impedance which effectively increases the output swing of the transmitters. - + - + - + dtr (20) data terminal ready dsrs (24) data signaling rate rs-232 inputs and outputs td (2) transmit data rts (4) request to send rd (3) receive data cts (5) clear to send signal ground (7) 15 8 13 7 14 16 - + 6 r2 r1 t2 t1 9 12 10 11 4 5 3 1 hin232 c1 1 f c2 1 f td rts rd cts select +5v inputs and outputs ttl/cmos figure 9. simple duplex rs-232 port with cts/rts handshaking 2 figure 10. combining two hin232s for 4 pairs of rs-232 inputs and outputs - + rs-232 inputs and outputs dtr (20) data terminal ready dsrs (24) data signaling rate select dcd (8) data carrier detect r1 (22) ring indicator signal ground (7) 15 8 13 7 14 2 - + 4 r2 r1 t2 t1 9 12 10 11 3 1 hin232 c1 1 f dtr dsrs dcd r1 +5v inputs and outputs ttl/cmos - + - + td (2) transmit data rts (4) request to send rd (3) receive data cts (5) clear to send 8 13 7 14 15 r2 r1 t2 t1 9 12 10 11 4 5 3 1 hin232 c1 1 f c2 1 f td rts rd cts inputs and outputs ttl/cmos - + 5 c2 1 f 16 c3 2 f 6 2 6 v- v+ - + c4 2 f 16 HIN231 thru hin241
