74LS175

74LS175 Quadruple D-Type Flip-Flop with Clear – TTL Logic IC

The 74LS175 is a dependable monolithic TTL integrated circuit featuring four positive-edge-triggered D-type flip-flops with complementary outputs and a direct clear input. Widely used in game room equipment repair and restoration — including pinball machines and arcade cabinets — this IC is a go-to replacement part for logic boards requiring reliable, edge-triggered data storage. Data present at the D inputs is transferred to the Q outputs on the positive-going edge of the clock pulse, ensuring precise, stable switching performance in demanding environments.

Fully compatible with most standard TTL circuits, the 74LS175 offers buffered clock and direct clear inputs along with individual data inputs for each of its four flip-flops, making it a versatile and essential component for electronics repair and parts inventory.
