Dual 4-Bit Binary Counters
±4-mA Output Drive at 5 V
Low Input Current of 1 µA Max Dual 4-Bit Binary Counters With IndividualClocks Direct Clear for Each 4-Bit Counter Can Significantly Improve System
Densities by Reducing Counter Package
Count by 50 Percent
description/ordering informationThe ’HC393 devices contain eight flip-flops and
additional gating to implement two individual 4-bit
counters in a single package. These devices
comprise two independent 4-bit binary counters,
each having a clear (CLR) and a clock (CLK)
input. N-bit binary counters can be implemented
with each package, providing the capability of
divide by 256. The ’HC393 devices have parallel
outputs from each counter stage so that any
submultiple of the input count frequency is
available for system timing signals.
ORDERING INFORMATION†Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are
