Overview
The CD74HCT175M96 is a high-speed CMOS logic Quad D-Type Flip-Flop with Reset, produced by Texas Instruments. This device is part of the 74HCT series, which is designed for high noise immunity and compatibility with TTL (Transistor-Transistor Logic) inputs. The CD74HCT175M96 is fabricated using silicon gate CMOS technology, offering the advantages of low power consumption and the ability to drive multiple LSTTL (Low-power Schottky Transistor-Transistor Logic) devices.
This component is obsolete, as indicated by Texas Instruments, but it remains relevant for existing designs and maintenance of older systems. It features a common clock and asynchronous reset for four D-type flip-flops, each with individual D-inputs and Q, Q complementary outputs.
