  • 3-state outputs: The outputs can be put in a high-impedance state, allowing multiple devices to share a common bus without interference.

Advantages and Disadvantages

Advantages

  • Efficient data storage and transfer with octal latching.
  • 3-state outputs enable easy sharing of a common bus.
  • Wide operating temperature range (-40°C to +85°C) allows for versatile applications.

Disadvantages

  • Propagation delay time of 6 ns (max) may limit high-speed applications.
  • Limited output current of ±24 mA may restrict certain load requirements.

Working Principles

The 74F373SC operates based on the principle of transparent latching. When the latch enable (LE) signal is high, the input data is directly transferred to the outputs. The latch holds the data until a new value is provided or the latch enable signal goes low.
