PIN AND FUNCTION COMPATIBLE

WITH 54/74LS393

The M54/74HC393 is a high speed CMOS DUAL

BINARY COUNTER fabricated in silicon gate

C2MOS technology. It has the same high speed

performance of LSTTL combined with true COMS

low power consumption.

This counter circuit contains independent ripple

carry counters and two 4-bit ripple carry binary

counters, which can be cascated to create a single

divide by 256 counter.

Each 4-bit counter is incremented on the high to low

transition (negative edge) of the clock input,and

each has an independent clear input. When clear is

set to low all four bits of each counter are set to a

low level. This enables count truncation and allows

the implementation

od divide by N counter

configurations.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
