Overview
The MC74LCX374DTR2G is a high-performance, non-inverting octal D-type flip-flop produced by onsemi. This component operates within a voltage range of 2.3 to 3.6 V and features 5 V tolerant inputs and outputs, making it compatible with 5 V TTL logic. It is designed for low-voltage CMOS applications and supports live insertion and withdrawal. The device consists of eight edge-triggered flip-flops with individual D-type inputs and 3-state true outputs, along with a buffered clock and output enable (OE) inputs common to all flip-flops.
