74LS175 Quad D-Type Flip-Flop with Clear
Package SOIC Series 74LS
74LS175 overview
The 74LS series of integrated circuits (ICs) was one of the most popular logic families of transistor-transistor logic (TTL) logic chips. 74LS series is a bipolar, low-power Schottky IC. 74LS175 positive-edge-triggered flip-flops utilize TTL circuitry to implement D-type flip-flop logic. All have a direct clear input and the quad (175) versions feature complementary outputs from each flip-flop.
