Overview
The Texas Instruments CD74HCT573M96 is an octal transparent D-type latch integrated circuit. This component is part of the HCT (High-Speed CMOS) logic family and is designed to operate within a voltage range of 4.5V to 5.5V. The device features eight latches with 3-state outputs, enabling it to drive bus lines without the need for interface or pull-up components. 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 buffered output-enable (OE) input allows the outputs to be placed in either a normal logic state or a high-impedance state, which is useful for bus applications.
