Overview
The SN74LVC1G373DCKR, produced by Texas Instruments, is a single D-type latch with a 3-state output. This device is designed to operate within a supply 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 latching of the output, allowing the Q outputs to follow the D inputs when LE is high and to latch the outputs when LE is 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.
