MM74HC393 Dual 4-Bit Binary Counter
September 1983 Revised January 2005
MM74HC393 Dual 4-Bit Binary Counter
General Description
The MM74HC393 counter circuits contain independent ripple carry counters and utilize advanced silicon-gate CMOS technology. The MM74HC393 contains two 4-bit ripple carry binary counters, which can be cascaded to create a single divide-by-256 counter. Each of the two 4-bit counters is incremented on the HIGHto-LOW transition (negative edge) of the clock input, and each has an independent clear input. When clear is set HIGH all four bits of each counter are set to a low level. This enables count truncation and allows the implementation of divide-by-N counter configurations. Each of the counters outputs can drive 10 low power Schottky TTL equivalent loads. This counter is functionally as well as pin equivalent to the 74LS393. All inputs are protected from damage due to static discharge by diodes to VCC and ground.

Note 4: For a power supply of 5V 10% the worst case output voltages (VOH, and VOL) occur for HC at 4.5V. Thus the 4.5V values should be used when designing with this supply. Worst case VIH and VIL occur at VCC = 5.5V and 4.5V respectively. (The VIH value at 5.5V is 3.85V.) The worst case leakage current (IIN, ICC, and IOZ) occur for CMOS at the higher voltage and so the 6.0V values should be used.
