DESCRIPTION The M74HC691 is an high speed CMOS DECADE/COUNTER REGISTER (3 STATE) fabricated with silicon gate C2MOS technology. The internal circuit is composed of 3 stages including buffer output, which offers high noise immunity and stable output. This device incorporates a synchronous counter, four bit D-type register, and quadruple two-line to one-line multiplexers with three-state outputs in a single 20 pin package. The counter can be programmed from the data inputs and have enable P and enable T inputs and a ripple carry output for easy expansion. The register/counter select input, R/C, selects the counter when low or the register when high for the three state-outputs, QA, QB, QC, and PIN CONNECTION AND IEC LOGIC SYMBOLS
QD. If the LOAD input (LOAD) is held "L" DATA input (A - D) are loaded into the internal counter at positive edge of counter clock input (CCK). In the counter mode, internal counter counts up at the positive of the counter clock. If the counter clear inputs (CCLR) is held "L", the internal counter is cleared asynchronously to the counter clock. The internal counter's outputs are stored in the output register at the positive edge of the register clock (RCK). If the register clear input (RCLR) is held "L" the register is cleared asynchronously to register clock. All inputs are equipped with protection circuits against static discharge and transient excess voltage.

CIN CPD
Input Capacitance Power Dissipation Capacitance (note 1)
1) CPD is defined as the value of the IC's internal equivalent capacitance which is calculated from the operating current consumption without load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC
