SN74LS109AD TI Flip Flop IC | 16-SOIC | Dual J-K, Positive-Edge Trigger

Product Overview

The SN74LS109AD is a dual J-K positive-edge-triggered flip-flop integrated circuit from Texas Instruments (TI), housed in a 16-pin SOIC package. It features individual J, K, clock, and direct clear inputs for each flip-flop, with complementary Q and Q̅ outputs. This device is designed for general-purpose storage and counting applications in digital systems, offering low power consumption and high noise immunity characteristic of the LS (Low-Power Schottky) family.
