CD74AC574E TI Flip-Flop | 20-PDIP | 1.5-5.5V, 8-Bit D-Type, 3-State

Product Overview

The CD74AC574E from Texas Instruments is an advanced high-speed CMOS octal D-type flip-flop with 3-state outputs. It operates from 1.5V to 5.5V, making it suitable for battery-powered and low-voltage applications. The device features eight edge-triggered flip-flops with individual D inputs and Q outputs, controlled by a common clock (CLK) and output enable (OE). When OE is low, the outputs are enabled; when high, they enter a high-impedance state. The CD74AC574E is ideal for bus-oriented systems requiring high drive capability and low power consumption.
