What are the key features of SN74HC373PWE4?
- 8 independent transparent D-type latches with active-low output enable for efficient 8-bit address bus demultiplexing
- HC/UH CMOS family compatible with both 3.3 V and 5 V logic levels, minimizing interface complexity in mixed-voltage systems
- 20-pin TSSOP package with 150 pF load drive capability enabling compact high-speed bus buffer designs
What is SN74HC373PWE4 used for?
The SN74HC373PWE4 is a standard octal latch used for address bus demultiplexing in microcontroller and microprocessor systems, where it captures the lower address byte during the address phase of multiplexed bus cycles. It serves as a transparent buffer in memory interfacing designs connecting CPUs to SRAM, EEPROM, and Flash devices operating at 3.3 V or 5 V. The 20-pin TSSOP package fits tightly routed PCBs in embedded controllers, FPGA peripheral boards, and data acquisition systems requiring reliable 8-bit bus latching.
