SN54LVC573A and SN74LVC573A are two transparent D-type latches that are designed for 2.7-V to 3.6-V VCC and 1.65-V to 3.6-V VCC operation.
The SN54LVC573A and SN74LVC573A are octal transparent D‑type latches featuring 3‑state outputs, designed for operation over a wide supply‑voltage range and suitable for buffer registers, I/O ports, and bus drivers. The devices include latch‑enable (LE) and output‑enable (OE) pins that control data latching and high‑impedance output states.
