High–Performance Silicon–Gate CMOS
The MC54/74HC393A is identical in pinout to the LS393. The device
inputs are compatible with standard CMOS outputs; with pullup resistors,
they are compatible with LSTTL outputs.
This device consists of two independent 4–bit binary ripple counters with
parallel outputs from each counter stage. A
÷
256 counter can be obtained
by cascading the two binary counters.
Internal flip–flops are triggered by high–to–low transitions of the clock
input. Reset for the counters is asynchronous and active–high. State
changes of the Q outputs do not occur simultaneously because of internal
ripple delays. Therefore, decoded output signals are subject to decoding
spikes and should not be used as clocks or as strobes except when gated
with the Clock of the HC393A.
Output Drive Capability: 10 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2 to 6 V
