not for new design recommended replacement a6810 bimos ii 10-bit serial-input, latched source drivers for -40 c to +85 c operation always order by complete part number, e.g., ucq5810af . the ucq5810af, UCQ5810EPF, and ucq5810lwf combine a 10-bit cmos shift register and accompanying data latches, control circuitry, bipolar sourcing outputs with dmos active pull-downs. designed primarily to drive vacuum-fluorescent displays, the 60 v and -40 ma output ratings also allow these devices to be used in many other peripheral power driver applications. the ucq5810af/epf/lwf feature reduced supply requirements (active dmos pull-downs) and lower saturation voltages when compared with the original ucq5810a. the cmos shift register and latches allow direct interfacing with microprocessor-based systems. with a 5 v supply, they will operate to at least 3.3 mhz. at 12 v, higher speeds are possible. use with ttl may require appropriate pull-up resistors to ensure an input logic high. a cmos serial data output enables cascade connections in applications requiring additional drive lines. similar devices are available as the ucq5811a (12 bits), ucq5812af/epf (20 bits), and ucq5818af/epf (32 bits). the ucq5810af/epf/lwf output source drivers are npn darlingtons capable of sourcing up to 40 ma. the dmos active pull-downs are capable of sinking up to 15 ma. for inter-digit blanking, all of the output drivers can be disabled and the dmos sink drivers turned on by the blanking input high. the ucq5810af is furnished in an 18-pin dual in-line plastic package. the UCQ5810EPF is furnished in a 20-lead plastic chip carrier. the ucq5810lwf is furnished in a wide-body, small-outline plastic package (soic) with gull-wing leads. copper lead frames, reduced supply current requirements, and lower output saturation voltages allow all devices to source 25 ma from all outputs continuously, over the entire operating temperature range. features high-speed source drivers 60 v minimum output breakdown improved replacements for tl4810b ucq5810af data sheet 26182.25b 2 3 4 5 6 7 8 910 11 12 13 14 15 16 17 18 serial data out load supply serial data in blanking logic supply strobe ground clock clk v st blnk dd bb v out 9 out 10 out 1 out 2 out 3 dwg. pp-029 out 8 out 7 out 6 out 5 out 4 1 latches register register latches absolute maximum ratings at t a = 25 c logic supply voltage, v dd ..................... 15 v driver supply voltage, v bb .................... 60 v continuous output current range, i out .......................... -40 ma to +15 ma input voltage range, v in ........................ -0.3 v to v dd + 0.3 v package power dissipation, p d (ucq5810af) ........................... 2.08 w* (UCQ5810EPF) ........................ 1.60 w* (ucq5810lwf) ........................ 1.33 w* operating temperature range, t a .................................. -40 c to +85 c storage temperature range, t s ................................ -55 c to +150 c *derate linearly to 0 w at +150 c. caution: cmos devices have input static protection but are susceptible to damage when exposed to extremely high static electrical charges. note that the ucq5810af (dual in-line package) and ucq5810lwf (small-outline ic package) are electrically identical and share a common terminal number assignment. low output saturation voltages low-power cmos logic and latches to 3.3 mhz data input rate active dmos pull-downs 5810 -f

transition of the clock input pulse. on succeeding clock pulses, the registers shift data information towards the serial data out- put. the serial data must appear at the input prior to the rising edge of the clock input waveform. information present at any register is trans- ferred to the respective latch when the strobe is high (serial-to-parallel conversion). the latches will continue to accept new data as long as the strobe is held high. applications where the latches are bypassed (strobe tied high) will require that the blanking input be high during serial data entry. when the blanking input is high, the output source drivers are disabled (off); the dmos sink drivers are on. the information stored in the latches is not affected by the blanking input. with the blanking input low, the outputs are controlled by the state of their respective latches. timing requirements (t a = +25 c,v dd = 5 v, logic levels are v dd and ground) a. minimum data active time before clock pulse (data set-up time) .......................................................................... 75 ns b. minimum data active time after clock pulse (data hold time) ............................................................................. 75 ns c. minimum data pulse width ................................................................ 150 ns d. minimum clock pulse width ............................................................... 150 ns e. minimum time between clock activation and strobe ....................... 300 ns f. minimum strobe pulse width ............................................................. 100 ns g. typical time between strobe activation and output transistion ......................................................................... 500 ns timing is representative of a 3.3 mhz clock. higher speeds may be attainable with increased supply voltage; operation at high temperatures will reduce the specified maximum clock frequency. e f clock data in strobe blanking out n a d b c g dwg. no. a-12,649a 5810-f 10-bit serial-input, latched source drivers for -40 c to +85 c operation www.allegromicro.com ucq5810af dimensions in inches (controlling dimensions) dimensions in millimeters (for reference only) notes: 1. exact body and lead configuration at vendor?
