Descriptions:

The SN74173N is a 4-bit D-type register with common clock (CLK) and master reset (MR) inputs. It features tri-state outputs, allowing multiple registers to share a common bus without interference.

Features:

  • Parallel Data Storage: Latches 4 bits of data on the rising edge of the clock.
  • Tri-State Outputs: Enables bus-oriented applications.
  • Master Reset (MR): Clears all register outputs when activated.
  • Output Enable (OE): Controls the tri-state outputs.
  • Wide Operating Voltage: Compatible with standard TTL logic levels.

This device is commonly used in data storage, buffering, and bus interfacing applications.
