What are the key features of CD74HC173M?

  • 4-bit D-type register with 3-state outputs for high-impedance bus sharing
  • Dual output enable pins provide independent control of output state
  • Wide supply voltage range: 2 V to 6 V for multi-rail system compatibility

What is CD74HC173M used for?

The CD74HC173M is suited for bus-oriented digital systems where multiple devices share a common data bus, thanks to its 3-state outputs and dual output enable control. It serves as a 4-bit holding register in microprocessor address latching and data pipeline buffering applications. The wide 2 V to 6 V supply range makes it compatible with both 3.3 V and 5 V logic systems.

Frequently Asked Questions

What output drive capability does the CD74HC173M offer, and how does that affect bus loading?

The CD74HC173M provides 3-state outputs with a maximum output low current of 7.8 mA (0.0078 A), allowing multiple devices to share a common bus without excessive loading. When outputs are disabled, they present high impedance, preventing bus contention in multi-driver designs.

How does the dual output enable feature help when integrating CD74HC173M into a 4-bit data bus architecture?

The dual output enable pins let designers independently gate the 4 stored bits onto a shared bus, enabling selective read-back with minimal logic. This is particularly useful in 4-bit wide bus segments operating at 5 V where multiple CD74HC173M devices are daisy-chained across 16-pin SOIC footprints.

Which supply voltage rails is the CD74HC173M compatible with, and does it support mixed 3.3 V and 5 V systems?

The CD74HC173M operates across a 2 V to 6 V supply range, making it fully compatible with both 3.3 V and 5 V logic rails. A 50 pF load capacitance rating ensures reliable switching performance in mixed-voltage systems without requiring level-shifting components.
