Overview
The MC74LCX16373DTR2G, produced by onsemi, is a high-performance, non-inverting 16-bit transparent latch. This device operates within a voltage range of 2.3 V to 3.6 V and is designed for low-voltage CMOS applications. It features byte-controlled operation, with each byte having separate Output Enable and Latch Enable inputs. The device is 5 V-tolerant on both inputs and outputs, making it compatible with 5 V TTL logic. It supports live insertion and withdrawal, and its outputs are TTL and LVCMOS compatible.
