Part Number: M74HC698
Function: CMOS Up / Down Decade Counter / Register
Package: DIP 20 Pin Type
Image and Pinouts:
The M74HC699, M74HC698 are high speed CMOS up/down counters fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The HC696/698 are BCD DECADE COUNTER, and the HC697/699 are 4-BIT BINARY COUNTER. Both devices have register. They count 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 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.
1. High Speed : f MAX = 50 MHz (Typ.) at Vcc = 5 V
2. Low Power Dissipation : Icc = 4 uA (Max.) at Ta = 25’C
3. High Noise Immunity : Vnih = Vnil = 28% Vcc (Min.)
4. Wide Operating Voltage Range : Vcc(OPR) = 2V to 6 V
