Overview
The SN74LVC1G373DCKRG4, produced by Texas Instruments, is a single D-type latch with a 3-state output. This device is designed to operate over a wide 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 allows the Q outputs to follow the data (D) inputs when high, and latch the Q outputs at the logic levels set up at the D inputs when low.
