Working Principles

The MM74HC373MTCX operates as an octal transparent latch with 3-state outputs. It can store data when the latch enable (LE) signal is high, and transfer the stored data to the output pins when the output enable (OE) signal is low. The non-inverting outputs provide a direct representation of the stored data. The integrated circuit is designed to operate at high speeds, making it suitable for applications that require fast data storage and transfer.
