Overview
The Texas Instruments 74LVC1G373DCKRG4 is a single D-type latch with a 3-state output, designed for operation over a wide voltage range of 1.65 V to 5.5 V. This device is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. The latch-enable (LE) input controls the latching of the data (D) inputs to the output (Q), allowing the outputs to be latched at the logic levels set up at the D inputs when LE is taken low. The device also features a buffered output-enable (OE) input that can place the output in either a normal logic state or a high-impedance state, which is useful for bus applications without the need for interface or pullup components.
