SN74F373DW

Overview

The SN74F373DW is an octal transparent D-type latch with three-state outputs manufactured by Texas Instruments. It belongs to the 74F logic series and features a non-inverting configuration. The device operates within a supply voltage range of 4.5 V to 5.5 V. It exhibits a propagation delay of 8.6 ns, with low-level output current capability of 24 mA and high-level output current of -3 mA. The component is housed in a 20-SOIC package and supports surface-mount installation. It functions across a temperature range of 0°C to 70°C.

Feature Summary

• Octal transparent D-type latch architecture providing eight independent data storage elements.
• Three-state outputs enable direct bus driving and system-wide data line sharing.
• High-speed switching performance characteristic of the 74F logic family.

Applications

• Registering data on microprocessor buses
• Buffering memory address lines
• Driving high-capacitance loads in digital systems

Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-20 package variant. Confirm RoHS compliance status through official documentation as manufacturing standards may evolve. Ensure the source document explicitly lists this part number to avoid confusion with similar F-series latches or different packaging options like tape-and-reel variants.

Selection Notes

Select this component when high-speed operation is required for octal data storage. The 74F series offers faster propagation delays compared to standard 74LS equivalents. Verify that the 4.5V to 5.5V operating voltage aligns with the target system power rails. Consider the 20-SOIC package dimensions for PCB layout constraints.

Part Context

This part is part of the broader SN74F373 family of octal latches. It shares functional similarities with other 74F series devices but is distinguished by its specific speed characteristics and package type. The DW suffix indicates a plastic small-outline package suitable for automated surface-mount assembly processes.
