SN74S74DR TI Flip-Flop | 14-SOIC | Dual D-Type, Positive-Edge Trigger

Product Overview

The SN74S74DR from Texas Instruments is a dual D-type positive-edge-triggered flip-flop with preset and clear functions. Housed in a 14-pin SOIC package, it features Schottky-clamped transistors for high speed and low power consumption. Each flip-flop has independent data (D), clock (CLK), preset (PRE), and clear (CLR) inputs, with complementary Q and Q̅ outputs. The device operates over a wide supply voltage range of 4.75 V to 5.25 V and is characterized for operation from 0°C to 70°C.
