Overview
The SN74LVC1G373 device, produced by Texas Instruments, is a single D-type latch designed for operation over a wide voltage range of 1.65 V to 5.5 V. This component is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. The latch-enable (LE) input allows the output (Q) to follow the data (D) input when high, and latches the output at the logic levels set up at the D inputs when LE is taken low. The device also features an active-low output-enable (OE) input that can place the output in a high-impedance state.
