74F393 - Dual 4-bit binary ripple counter

Description

The 74F393 is a Dual Ripple Counter with separate Clock (CPn) and Master Reset (MR) inputs to each counter.

The two counters are identified by the “a” and “b” suffixes in the pin configuration.

The operation of each half of the 74F393 is the same.

Features

  • Two 4-bit binary counters.
  • Two Master Resets to clear each 4-bit counter individually.

INTEGRATED CIRCUITS 74F393 Dual 4-bit binary ripple counter Product specification IC15 Data Handbook 1988 Nov 01 Philips Semiconductors Philips Semiconductors Product specification Dual 4-bit binary ripple counter 74F393 FEATURES • Two 4-bit binary counters • Two Master Resets to clear each 4-bit counter individually DESCRIPTION The 74F393 is a Dual Ripple Counter with separate Clock (CPn) and Master Reset (MR) inputs to each counter. The two counters are identified by the “a” and “b” suffixes in the pin configuration. The operation of each half of the 74F393 is the same. The counters are triggered by a High-to-Low transition of the Clock (CPa and CPb) inputs. The counter outputs are internally connected to provide Clock inputs to succeeding stages.
