The 74VCX16373MTDX is a Type D transparent latch manufactured by Fairchild Semiconductor (or onsemi). Here are some details about the 74VCX16373MTDX:
Type: logic-lock pin
Logical type: Type D transparent latch
Circuit: 8:8
Output type: three states
Voltage - Power supply: 1.2V ~ 3.6V
Delay time - Propagation: 1.5ns
Current - Output high, low: 24mA, 24mA
Operating temperature: -40°C ~ 85°C

This latch has two separate 8-bit Type D transparent latches, each with a three-state output. They are particularly suitable for use as buffer registers or I/O ports in microprocessor and microcontroller systems. These latches allow high-speed data transfer between data buses while providing low-power operation.
