SN54AHCT74 - Dual Positive-Edge-Triggered D-Type Flip-Flops

📥 Download Datasheet

General Description

The ’AHCT74 dual positive-edge-triggered devices are D-type flip-flops.

A low level at the preset (PRE) or clear (CLR) inputs sets or resets the outputs, regardless of the levels of the other inputs.

When PRE and CLR are inactive (high), data at the data (D) input meeting the setup time requirements is transferred to the outputs on the positive-going edge of the clock pulse.

Overview

SN54AHCT74, SN74AHCT74 SCLS263Q – DECEMBER 1995 – REVISED JULY 2023 SNxAHCT74 Dual Positive-Edge-Triggered D-Type Flip-Flops With Clear And Preset.
