TECHNICAL DATA
Dual 4-Stage Binary Ripple Counter
High-Performance Silicon-Gate CMOS
device inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LS/ALSTTL outputs.
with parallel outputs from each counter stage. A÷256 counter can be
obtained by cascading the two binary counters.
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 IN74HC393A.
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2.0 to 6.0 V
• Low Input Current: 1.0 µA
• High Noise Immunity Characteristic of CMOS Devices
The IN74HC393A is identical in pinout to the LS/ALS393. The
This device consists of two independent 4-bit binary ripple counters
Internal flip-flops are triggered by high-to-low transitions of the clock
