JM38510/66309BCA General Description

The 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.

Key Features

Wide Operating Voltage Range of 2 V to 6 V
Outputs Can Drive Up To 10 LSTTL Loads
Low Power Consumption, 80-µA Max I_CC
Typical t_pd = 13 ns
±4-mA Output Drive at 5 V
Low Input Current of 1 µA Max
Dual 4-Bit Binary Counters With Individual Clocks
Direct Clear for Each 4-Bit Counter
Can Significantly Improve System Densities by Reducing Counter Package Count by 50 Percent
