74AHC573PW,118

The 74AHC573PW,118 from Nexperia is an 8-bit D-type transparent latch featuring 3-state outputs. This device is designed for versatility, offering a wide supply voltage range from 2.0 V to 5.5 V, making it suitable for various mixed-voltage environments. Its inputs are overvoltage tolerant up to 5.5 V.

The latch enable (LE) and output enable (OE) inputs control the device's operation. When LE is HIGH, data at the inputs enters the latches, and the outputs are transparent. When LE transitions from HIGH to LOW, the latches store the input data present at the set-up time. A HIGH on the OE input places the outputs in a high-impedance OFF-state, without affecting the latches' stored information.

Key features include balanced propagation delays and Schmitt-trigger action on all inputs, ensuring high noise immunity. The device operates across a temperature range of -40°C to +125°C. It is supplied in a 20-TSSOP package, suitable for surface mounting.

This latch is functionally identical to the 74AHC373 and 74AHCT373 series. The 74AHC573 variant uses CMOS input levels, while the 74AHCT573 variant uses TTL input levels. ESD protection is provided, meeting HBM class 2 and CDM class C3 standards, and latch-up performance exceeds 100 mA.
