Overview
The MC74VHC74DR2G, produced by onsemi, is a high-speed CMOS D-Type Flip-Flop integrated circuit. Fabricated with silicon gate CMOS technology, this device achieves high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining the low power dissipation characteristic of CMOS technology. The MC74VHC74DR2G is part of the MC74VHC74 series, which includes dual D-Type Flip-Flops with Set and Reset functions. These flip-flops are designed to transfer the signal level applied to the D input to the Q output during the positive-going transition of the Clock pulse. The device is also capable of acting as a level converter for interfacing 3.3 V to 5.0 V systems due to its full 5.0 V CMOS level output swings.
