概要
Description
The SN74HC573ADW is a high-speed CMOS octal D-type latch with 3-state outputs, manufactured by Texas Instruments. It is part of the 74HC series and is designed to meet the needs of both low-power and high-performance applications. This device features eight D-type latches, each possessing a latch-enable (LE) input and an output-enable (OE) control for 3-state output operation.
When the LE input is high, data at the D inputs is latched. With the OE input, you can control whether the outputs are active or in a high-impedance state, facilitating easy bus interfacing. The SN74HC573ADW operates from a supply voltage range of 2V to 6V, making it versatile for various digital systems. It supports high-speed operations with typical propagation delays and low power consumption, thanks to its CMOS technology. Encased in a SOIC (Small Outline Integrated Circuit) package, it ensures reliable performance in a compact form, suitable for space-constrained applications. This device is commonly used in applications requiring temporary data storage, inter-device communication, and data buffering.
