The XD74HC373 from Xinluda is an octal D-type transparent latch with 3-state outputs, manufactured on a high-speed silicon-gate CMOS process. It is a pin-for-pin and function-compatible implementation of the industry-standard 74HC373 logic device, making it a versatile building block for address latching, data buffering, and bus-oriented designs.
The device contains eight D-type latches with common 3-state output control. The latch enable (LE) input controls all eight latches simultaneously: when LE is HIGH the latches are transparent and each output follows its corresponding D input; when LE goes LOW, the data present is held. A separate active-LOW output enable (OE) input places the eight outputs into a high-impedance state without affecting the stored data, allowing the part to drive shared buses directly.
The XD74HC373 is a hard-to-find part with little to no authorized-distributor stock. Pacific Component Xchange specializes in sourcing scarce, obsolete, and end-of-life logic devices and power-management ICs like this Xinluda latch. Our independent global network lets us locate, authenticate, and deliver components that mainline catalog distributors no longer carry.
Every order is backed by our commitment to authenticity and quality, with inspection and traceability to guard against counterfeit risk. We ship worldwide and consolidate hard-to-find line items so your build stays on schedule. Request a quote (RFQ) today and our sourcing team will respond with availability, lead time, and pricing for the XD74HC373.
The XD74HC373 is an 8-bit octal D-type transparent latch with 3-state outputs from Xinluda. It is built on high-speed CMOS technology and is functionally equivalent to the industry-standard 74HC373 logic device.
Yes. The XD74HC373 is a pin-for-pin and function-compatible implementation of the standard 74HC373 octal transparent latch, so it can be used as a drop-in replacement in most designs that specify a 74HC373.
As a member of the 74HC logic family, the XD74HC373 operates over a wide supply voltage range of 2.0 V to 6.0 V with low static CMOS power dissipation.
When Latch Enable (LE) is HIGH the latches are transparent and outputs follow the D inputs; when LE is LOW the data is held. The active-LOW Output Enable (OE) places the eight outputs into a high-impedance state without changing the latched data, allowing the device to share a bus.
The XD74HC373 is typically offered in 20-pin through-hole DIP and surface-mount SOP packages. Contact Pacific Component Xchange to confirm the specific package and date codes available for your RFQ.
The XD74HC373 has limited authorized-distributor availability, so pricing and lead time depend on current sourcing. Pacific Component Xchange specializes in locating hard-to-find parts like this; submit an RFQ and our team will return availability and a quote.
