High-Performance Silicon-Gate CMOS
The IN74HC393 is identical in pinout to the LS/ALS393. The
device inputs are compatible with standard CMOS outputs; with
pullup resistors, they are compatible with LS/ALSTTL 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 becaue 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 IN74HC393.
