Frequently Asked Questions

What is the supply voltage range and output drive capability of the CD74ACT573M?

The CD74ACT573M operates from a 4.5V to 5.5V supply voltage. It provides a maximum output low current (IOL) of 24mA, making it suitable for driving standard TTL and CMOS bus loads with up to 50pF load capacitance.

What are typical applications for the CD74ACT573M octal latch?

The CD74ACT573M is commonly used in address and data bus buffering for microprocessors, memory interfacing, I/O port expansion, and industrial control systems. Its 3-state outputs and transparent latch architecture make it ideal for shared-bus and data-demultiplexing applications.

How does the CD74ACT573M differ from the CD74ACT373?

The CD74ACT573M is the broadside pinout version of the CD74ACT373. Both are octal transparent D-type latches with 3-state outputs, but the 573 places all data inputs on one side and all outputs on the opposite side, simplifying PCB routing compared to the 373's alternating input/output pin arrangement.

What package does the CD74ACT573M use and what are its dimensions?

The CD74ACT573M is housed in a 20-pin SOIC (Small Outline Integrated Circuit) surface-mount package. This compact package is well-suited for high-density PCB designs where through-hole components are not practical.
