The 74HC573D is an integrated circuit (IC) component that belongs to the 74HC series of logic devices. It is a octal D-type transparent latch with 3-state outputs, designed for general-purpose storage applications in digital systems. Here are some key features of the 74HC573D:
1. Octal D-type latch: The 74HC573D can store data in eight D-type flip-flops (latches). Each latch can hold a single bit of data and can be individually controlled.
2. Transparent latch: The IC has a transparent enable input (G2), which, when active, allows the data on the data inputs (D0-D7) to propagate through to the outputs (Q0-Q7). This enables real-time data transfer from input to output.
3. 3-state outputs: The 74HC573D provides 3-state outputs (Q0-Q7), which means they can be disconnected from the rest of the circuit when not required. This feature facilitates bus-oriented applications, where multiple devices can share a common communication line.
4. High-speed operation: The IC is designed for high-speed operation and can typically operate at frequencies up to 95 MHz. This enables efficient and quick data transfer in digital systems.
5. Wide supply voltage range: The 74HC573D can operate with a wide supply voltage range of 2V to 6V
