Overview
The CD74HCT573M96G4 is an octal transparent D-type latch produced by Texas Instruments. This component is part of the 74HCT series and is designed to operate within a supply voltage range of 4.5V to 5.5V. It features eight D-type latches with 3-state outputs, making it suitable for various digital logic applications. When the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs, and when LE is low, the Q outputs are latched at the logic levels of the D inputs. The device also includes a buffered output-enable (OE) input that can place the outputs in either a normal logic state or a high-impedance state, which is useful for bus applications.
