74LS393 Datasheet Dual 4-bit Binary Counter

Manufacturer: Fairchild (now onsemi)

Overview: DM74LS393 Dual 4-Bit Binary Counter August 1986 Revised March 2000 DM74LS393 Dual 4-Bit Binary.

General Description

Each of these monolithic circuits contains eight masterslave flip-flops and additional gating to implement two individual four-bit counters in a single package.

The DM74LS393 comprises two independent four-bit binary counters each having a clear and a clock input.

N-bit binary counters can be implemented with each package providing the capability of divide-by-256.

Key Features

  • s Dual version of the popular DM74LS93 s DM74LS393 dual 4-bit binary counter with individual clocks s Direct clear for each 4-bit counter s Dual 4-bit versions can significantly improve system densities by reducing counter package count by 50% s Typical maximum count frequency 35 MHz s Buffered outputs reduce possibility of collector commutation Ordering Code: Order Number DM74LS393M DM74LS373N Package Number M14A N14A Package.
