The document describes the features and characteristics of the SN54LVC573A and SN74LVC573A octal transparent D-type latches. These devices feature 3-state outputs, operate from 1.65V to 3.6V VCC, accept input voltages up to 5.5V, and provide excellent ESD protection and noise immunity.
The SN54LVC573A and SN74LVC573A are octal transparent D‑type latches with 3‑state outputs, suitable for buffer registers, I/O ports, bus drivers and working registers. The devices operate from low‑voltage supplies and feature partial‑power‑down mode, high‑impedance output control, and robust ESD protection.
The document provides detailed pin configurations, electrical and timing characteristics, recommended operating conditions, packaging options, mechanical dimensions, and legal notices. Ordering information and package drawings are also included.
