Frequently Asked Questions
What is the SN74HC373NE4 and what are its key electrical specifications?
The SN74HC373NE4 is a high-speed CMOS octal D-type transparent latch with tri-state outputs from Texas Instruments. It belongs to the HC/UH logic family, supports a load capacitance of 150pF, operates with unidirectional count direction, and uses an active-low enable control. The 20-pin DIP package suits through-hole PCB designs.
What are the typical applications of the SN74HC373NE4?
The SN74HC373NE4 is commonly used in microprocessor bus buffering, address latching for memory systems, I/O port expansion, and bus demultiplexing. Its tri-state outputs make it ideal for shared bus architectures in embedded systems, industrial controllers, and communication hardware requiring 8-bit transparent data latching.
What package does the SN74HC373NE4 come in and are there compatible alternatives?
The SN74HC373NE4 comes in a 20-pin dual-in-line (R-PDIP-T20) through-hole package. Compatible alternatives include the SN74HC373D (SOIC-20 surface-mount) and SN74HC373PW (TSSOP-20). All variants share the same logic function and pinout, differing only in package type and thermal characteristics.
Is the SN74HC373NE4 RoHS compliant and what does the 'E4' suffix mean?
Yes, the SN74HC373NE4 is fully RoHS compliant. The 'E4' suffix corresponds to JESD-609 code e4, indicating the device is lead-free (Pb-free) and halogen-free, meeting international environmental standards. The Pb-free code is confirmed as 'Yes' in Texas Instruments' product specifications.
