Frequently Asked Questions
What is the CD74HC173PWR and what logic function does it perform?
The CD74HC173PWR is a quad 4-bit D-type flip-flop with 3-state outputs. It stores a 4-bit data word on the rising clock edge and can place its outputs in a high-impedance state via two independent active-low output-enable inputs, making it ideal for shared bus applications.
What supply voltage range does the CD74HC173PWR support?
The CD74HC173PWR operates over a supply voltage range of 2V to 6V, which covers standard 3.3V and 5V logic systems. This wide range allows it to be used in low-voltage portable designs as well as traditional 5V TTL-compatible systems.
What package and pin count does the CD74HC173PWR use?
The CD74HC173PWR is packaged in a 16-pin Small Outline IC (SOIC) surface-mount package, JESD-30 code R-PDSO-G16. The SOIC footprint balances compact board layout with easy hand soldering and is widely supported by standard PCB assembly processes.
How does the dual output-enable feature of the CD74HC173PWR work?
The device has two independent active-low output-enable (OE) pins that must both be asserted low to enable the outputs. If either OE pin is high, all four outputs enter the high-impedance (tri-state) mode. This dual-control architecture allows fine-grained bus access control from two separate logic sources.
Is the CD74HC173PWR compatible with TTL logic levels?
Yes, the CD74HC173PWR is from the HC CMOS family, which is designed with TTL-compatible input thresholds when operated at 5V. This makes it directly interoperable with 74LS, 74ALS, and other TTL-level logic families without additional level translation in 5V systems.
