CD74AC112E TI Flip-Flop | 16-PDIP | Dual J-K, Positive-Edge Trigger

Product Overview

The CD74AC112E from Texas Instruments is a dual J-K flip-flop with positive-edge trigger, designed for high-speed CMOS logic applications. It operates over a wide voltage range of 1.5V to 5.5V, making it suitable for battery-powered and low-voltage systems. The device features individual J, K, clock, and reset inputs for each flip-flop, providing flexible logic design capabilities. Housed in a 16-pin PDIP package, it is ideal for through-hole PCB assembly and prototyping.
