SN74AHCT74 Datasheet Dual Positive-edge-triggered D-type Flip-flops

Manufacturer: Texas Instruments

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

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.

Key Features

  • Operating range of 4.5 V to 5.5 V.
  • Low power consumption, 10-µA maximum ICC.
  • ±8-mA output drive at 5 V.
  • Inputs are TTL-voltage compatible.
  • Latch-up performance exceeds 250 mA per JESD 17 2.
