Overview
The 74HC573PW/AU118, produced by Nexperia USA Inc., is an 8-bit D-type transparent latch with 3-state outputs. This component is part of the 74HC series and is housed in a 20-pin TSSOP (Thin Shrink Small Outline Package) package. It is designed to operate within a voltage range of 2.0 to 6.0 volts, making it versatile for various electronic designs.
The device features latch enable (LE) and output enable (OE) inputs. When the LE input is HIGH, the latches are transparent, allowing the output to change each time the corresponding D-input changes. When LE is LOW, the latches store the information present at the inputs a set-up time preceding the HIGH-to-LOW transition of LE. A HIGH on the OE input causes the outputs to assume a high-impedance OFF-state without affecting the state of the latches.
