SN74AC74D

Flip Flops Overview

The SN74AC74D is a dual D-type flip-flop from the Texas Instruments 74AC logic series, housed in a 14-pin SOIC surface-mount package. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range of -40°C to +85°C. The device features a propagation delay of 9 ns, with high-level and low-level output currents rated at -24 mA and 24 mA respectively. It includes independent clock, data, preset, and clear inputs for each flip-flop.
