What are the key features of CD74HC173MG4?
- 4-bit quad D-type flip-flop with dual independent output-enable controls for flexible bus driving
- High-speed HC/UH CMOS family with 50 pF load capacitance rating for reliable signal integrity on capacitive bus lines
- Low output sink current of 7.8 mA per pin minimizes power consumption in 3-state bus applications
- RoHS-compliant 16-pin SOIC (R-PDSO-G16) packaging for standard through-board assembly and space-efficient layouts
What is CD74HC173MG4 used for?
The CD74HC173MG4 is used in digital bus buffering and data storage applications where 4 parallel data bits must be latched and selectively driven onto a shared bus using the dual output enable pins. It suits microprocessor interface designs, memory address latching, and FPGA I/O expansion boards operating on 3.3 V or 5 V HC-family logic rails. The device is also a standard choice for educational and prototyping platforms requiring straightforward 4-bit register functionality.

Frequently Asked Questions
What is the output current capability of the CD74HC173MG4 and how does it affect bus fan-out?
The CD74HC173MG4 provides a maximum output sink current of 7.8 mA (I_OL) per pin, which is sufficient to drive standard HC-family CMOS loads at 50 pF load capacitance. In a typical 5 V system, this allows the 16-pin SOIC device to fan out to several HC inputs simultaneously without violating noise margin or propagation delay specifications.
How do the dual output enable pins on the CD74HC173MG4 benefit 4-bit bus designs?
Two independent active-low output enable inputs allow the 4-bit outputs to be tri-stated, isolating the register from the bus without affecting stored data. This feature supports wired-OR bus architectures and multi-master designs where multiple 4-bit registers share a common data bus, reducing glitch risk during arbitration transitions on 3.3 V or 5 V HC-logic systems.
Which logic family is the CD74HC173MG4 part of, and does it interoperate with 74LS or TTL devices?
The CD74HC173MG4 belongs to the HC/UH high-speed CMOS family, which is fully compatible with TTL input levels, accepting inputs that meet standard 2 V logic-high and 0.8 V logic-low thresholds. Its JESD-609 e4 Pb-free rating and 16-pin SOIC package make it a direct drop-in replacement for legacy 74HC173 designs, while supporting mixed HC and LS logic environments at supply voltages from 2 V to 6 V.
