SN74LS112AN TI Dual J-K Flip-Flop | 16-PDIP | 3V to 15V, 45MHz

Product Overview

The SN74LS112AN from Texas Instruments is a dual J-K negative-edge-triggered flip-flop featuring individual J, K, clock, and asynchronous set/reset inputs. It is designed for general-purpose storage and counting applications in digital systems. The device operates from a wide supply voltage range of 3V to 15V and offers typical clock frequency up to 45MHz. Housed in a 16-pin PDIP package, it is ideal for through-hole PCB designs requiring robust logic functions.
