74LS393 Dual 4-Bit Binary Counter - (AD24488)

Description:

Each of these monolithic circuits contains eight master-slave flip-flops and additional gating to implement two individual four-bit counters in a single package. The DM74LS393 consists of two independent four-bit binary counters, each with a clear and a clock input. N-bit binary counters may be implemented; each package provides the capability of dividing by 256. The DM74LS393 has parallel outputs from each counter stage so that any submultiple of the input count frequency is available for system timing signals.

Features:

- Dual Version of the Popular DM74LS93

- DM74LS393 Dual 4-Bit Binary Counter with Individual Clocks

- Direct Clear for Each 4-Bit Counter

- Dual 4-Bit Versions Can Significantly Improve System Density by Reducing Counter Package Count by 50%

- Typical Maximum Count Frequency: 35 MHz

- Buffered Outputs Reduce the Possibility of Collector Commutation
