SN54HC74FK - Dual D-Type Positive-Edge-Triggered Flip-Flops

Download the SN54HC74FK datasheet PDF. This datasheet also covers the SN54HC74 variant, as both devices belong to the same dual d-type positive-edge-triggered flip-flops family and are provided as variant models within a single manufacturer datasheet.

General Description

The SNx4HC74 devices contain two independent D-type positive-edge-triggered flip-flops with asynchronous preset and clear pins for each.

Key Features

  • Buffered inputs.
  • Wide operating voltage range: 2 V to 6 V.
  • Wide operating temperature range: -40°C to +85°C.
  • Supports fanout up to 10 LSTTL loads.
  • Significant power reduction compared to LSTTL logic ICs 2.
