74LS175 DIP Quad D-Type Flip-Flop With Clear

The 74LS175 is a high speed TTL integrated circuit containing four independent D-type flip-flops with a common clock and a common asynchronous clear input. A distinguishing feature of this device is that it provides both true (Q) and complementary (Q BAR) outputs for each flip-flop. This dual-output configuration eliminates the need for external inverters in many applications, simplifying the design of complex logic circuits and signal steering networks.

Information at the D inputs is transferred to the outputs on the positive-going transition of the clock pulse. The common clear input is active low and operates independently of the clock; when pulled low, it immediately sets all true outputs to a low logic level and all complementary outputs to a high logic level. The 74LS175 is widely used for data storage, shift registers, and as a synchronization element in high-speed digital systems.
