Frequently Asked Questions
What is the CD74HC573M and how many bits does it latch?
The CD74HC573M is an 8-bit (octal) transparent latch with 3-state outputs. It stores 8 bits of data when the latch enable (LE) input is low, making it ideal for address latching and data bus buffering in digital systems.
What logic family does the CD74HC573M belong to and what is its supply voltage range?
The CD74HC573M belongs to the HC (High-speed CMOS) logic family, which operates over a wide 2V to 6V supply voltage range. HC-family devices offer fast switching speeds with CMOS-level low power dissipation, suitable for modern embedded and digital logic designs.
What is the difference between the CD74HC573M and the 74HC373?
Both the CD74HC573M and 74HC373 are octal transparent latches with 3-state outputs, but they differ in pinout. The 573 uses a broadside pinout where inputs are on one side and outputs on the other, while the 373 has inputs and outputs interleaved. This makes the 573 easier to route on PCBs where bus signals flow in one direction.
What package does the CD74HC573M come in?
The CD74HC573M is available in a 20-pin SOIC (Small Outline Integrated Circuit, JESD-30 code R-PDSO-G20) package. This surface-mount package is widely supported by PCB assembly processes and provides good thermal and electrical performance.
What are typical applications for the CD74HC573M?
Common applications include address bus latching in 8051 and other microcontroller systems, data bus buffering, memory address decoding, I/O port expansion, and FPGA interface boards. Its 3-state output allows multiple devices to share a common bus without contention.
