The SN74LVC573ANS from Texas Instruments is a high-performance, octal transparent D-type latch designed for 2-V to 3.6-V VCC operation. This integrated circuit (IC) is part of the LVC family, which is known for its low-voltage operation and compatibility with mixed-voltage system environments.

Key Features

• Operates from 2 V to 3.6 V, suitable for low-voltage applications.
• Maximum UHC output current of ±24 mA.
• IOFF supports live insertion, partial-power-down mode, and back-drive protection.
• Support for mixed-mode voltage operation on all ports.
• Latch-up performance exceeds 250 mA per JESD 17.
• ESD protection exceeds JESD 22.

Product Description

The SN74LVC573ANS is an octal transparent D-type latch with 3-state outputs. It is designed specifically to improve both the performance and density of three-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. With its wide operating voltage range and high-speed operation, it is suitable for interfacing with microprocessors and can be used in a broad range of applications.

Each latch has a separate OE (Output Enable) input and LE (Latch Enable) input. When LE is high, data at the inputs enter the latches. In this condition, the latches are transparent, i.e., a latch output will change each time its corresponding D-input changes. When LE is low, the latches store the information that was present at the D-inputs a setup time preceding the high-to-low transition of LE. The outputs are controlled by the OE input. When OE is high, the outputs are in a high-impedance state.

Texas Instruments' SN74LVC573ANS is characterized for operation from -40°C to 85°C, ensuring reliability across a wide range of temperatures, making it an ideal choice for industrial and consumer applications.
