What are the key features of CD74HC173NSRE4?
- Quad D-type flip-flop with 4-bit storage capacity and dual independent output enable controls for flexible bus-driving applications
- High-speed CMOS technology with propagation delay as low as 7 ns at 6V, enabling fast digital data latching in 2V to 6V systems
- Tri-state outputs with 6mA sink current (I_OL = 6mA) allow direct connection to shared data buses without contention
What is CD74HC173NSRE4 used for?
The CD74HC173NSRE4 is ideal for data storage and bus-driving applications in industrial control systems, embedded processor interfaces, and digital logic designs operating from 2V to 6V. Its quad D-type structure with dual output enable makes it well-suited for register-based data buffering between microcontrollers and peripheral devices. Common use cases include address latching in memory systems and temporary data storage in signal processing pipelines.

Frequently Asked Questions
What supply voltage range does the CD74HC173NSRE4 support, and how does this affect system design?
The CD74HC173NSRE4 operates from 2V to 6V supply voltage, making it compatible with both 3.3V and 5V logic systems. This wide range allows designers to use a single component across diverse power domains without level-shifting circuitry, simplifying BOM and reducing board space in mixed-voltage industrial designs.
How does the dual output enable feature of CD74HC173NSRE4 benefit bus arbitration designs?
The dual output enable (OE1 and OE2) pins allow the 4-bit tri-state outputs to be independently gated, supporting 6mA sink current per output. This lets multiple CD74HC173NSRE4 devices share a common bus without signal contention, which is critical in multi-master digital systems where data must be selectively driven onto 8-bit or 16-bit buses.
When should designers choose CD74HC173NSRE4 over a standard 74HC374 octal flip-flop?
CD74HC173NSRE4 is preferred when only 4 bits of registered storage are needed and dual output-enable control is required, reducing pin count versus the 20-pin 74HC374. Its 16-pin SOIC package saves approximately 30% board area compared to 20-pin alternatives, making it optimal for compact PCB layouts in space-constrained embedded controller and PLC applications.
What is the propagation delay and maximum clock frequency for CD74HC173NSRE4?
At 5V supply, the CD74HC173NSRE4 achieves a typical clock-to-output propagation delay of approximately 11 ns and supports clock frequencies up to 74 MHz, well within the HC-family speed grade. At 50pF load capacitance, outputs transition reliably, ensuring data integrity in high-speed 4-bit data latching applications.
