Overview
The 74LVC573APW,118 is an 8-bit D-type transparent latch produced by Nexperia USA Inc. This device is part of the 74LVC logic family and features 3-state outputs, making it versatile for various digital circuit applications. The latch includes latch enable (LE) and output enable (OE) inputs, allowing for precise control over data storage and output states. When the LE input is HIGH, the latches are transparent, and the output changes with each corresponding D-input change. When LE is LOW, the latches store the information present at the inputs before the HIGH-to-LOW transition of LE. A HIGH on the OE input causes the outputs to enter a high-impedance OFF-state without affecting the latch state.

The logic family of the 74LVC573APW,118 is 74LVC.
- What type of latch is the 74LVC573APW,118?
The 74LVC573APW,118 is an 8-bit D-type transparent latch.
- What is the package type of the 74LVC573APW,118?
The package type is TSSOP-20.
- What is the supply voltage range for the 74LVC573APW,118?
The supply voltage range is from 1.2 V to 3.6 V.
- Does the 74LVC573APW,118 support mixed voltage environments?
- What is the function of the latch enable (LE) input?
The latch enable (LE) input controls whether the latches are transparent or store the input data. When LE is HIGH, the latches are transparent; when LE is LOW, the latches store the data.
- What is the function of the output enable (OE) input?
A HIGH on the output enable (OE) input causes the outputs to assume a high-impedance OFF-state without affecting the latch state.
- Does the 74LVC573APW,118 have ESD protection?
- What are the operating temperature ranges for the 74LVC573APW,118?
- What is the significance of the IOFF circuitry in the 74LVC573APW,118?
OFF circuitry provides partial power-down mode operation, preventing backflow current through the device when it is powered down.
