Overview
The SN74ACT573PWR is an octal D-type transparent latch with 3-state outputs, manufactured by Texas Instruments. This device is part of the ACT family, known for its high-speed and low-power consumption. It operates within a supply voltage range of 4.5V to 5.5V, making it suitable for a variety of digital logic applications. The SN74ACT573PWR is particularly useful for driving highly capacitive or relatively low-impedance loads, making it ideal for buffer registers, I/O ports, bus drivers, and working registers.
