Overview
The MC74HCT74ADR2G, produced by onsemi, is a dual D flip-flop integrated circuit with set and reset capabilities. It is designed to be compatible with LSTTL (Low-power Schottky Transistor-Transistor Logic) inputs and can interface directly with CMOS, NMOS, and TTL logic circuits. This device is particularly useful for level conversion between different logic families and is part of onsemi's high-performance silicon-gate CMOS family.
The MC74HCT74ADR2G consists of two D flip-flops, each with individual set, reset, and clock inputs. The data at the D-input is transferred to the corresponding Q output on the next positive-going edge of the clock input. Both Q and Q' outputs are available from each flip-flop, and the set and reset inputs are asynchronous.
