Overview
The SN74LVC1G373DBVR, produced by Texas Instruments, is a single D-type latch with a 3-state output. This device is designed to operate within a voltage range of 1.65 V to 5.5 V, making it versatile for various applications. It is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. The latch-enable (LE) input controls the output, allowing the Q outputs to follow the D inputs when LE is high and latching the Q outputs when LE is low.
