The M54/74HCT393 is a high speed CMOS DUAL
BINARY COUNTER fabricated in silicon gate
C
2
MOS technology. It has the same high speed
performance of LSTTL combined with true COMS
low powerconsumption.
This counter circuit contains independent ripple
carry counters and two 4-bit ripple carry binary
counters, which can be cascated to create a single
divideby 256 counter.
Each 4-bit counter isincremented on thehightolow
transition (negative edge) of the clock input,and
each has an independent clear input. When clear is
set to high all four bits of each counter are set to a
low level. This enables counttruncation and allows
the
implementation
of
configurations.
This integrated circuit has input and output
characteristics that are fully compatible with 54/74
LSTTL logic families. M54/74HCT devices are
designed to directly interface HSC
2
MOS systems
with TTL and NMOS components. They are also
plug in replacements for LSTTL devices giving a
reduction of power consumption.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
