The
KK
74HC393A 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 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
KK
74HC393A.
