DESCRIPTION The M74HC696 is an high speed CMOS UP / DOWN COUNTER REGISTER (3 STATE) fabricated with silicon gate C2MOS technology. The M74HC696 is a BCD DECADE COUNTER with REGISTER. The device counts on the positive edge of the counter clock input (CCK) when selected by the "Counter Mode". If the input U/D is held "H", the internal counter counts up, and held "L", counts down. The internal counter's outputs are stored in the output register at the positive edge of register clock (RCK).
The counter features enable P and enable T 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 QD. Both the counter clock CCR and register clock RCK are positive-edge triggered. The counter clear CCLR is active low and is asynchronous. 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 f IN + ICC/2 (per circuit)
