SN74ALS74ADB TI Flip-Flop IC | D-Type, Dual, Positive Edge | 4.5V-5.5V, 4.5ns

Product Overview

The SN74ALS74ADB is a dual D-type positive-edge-triggered flip-flop integrated circuit from Texas Instruments (TI). It features individual data (D), clock (CLK), clear (CLR), and preset (PR) inputs, along with complementary Q and Q̅ outputs. This device is designed for high-performance digital systems requiring reliable data storage and transfer. The SN74ALS74ADB operates over a wide supply voltage range of 4.5V to 5.5V and offers a typical propagation delay of 4.5ns, making it suitable for high-speed applications. It is available in a small SSOP package (DB), ideal for space-constrained designs.
