SN74F573DW

Overview

The SN74F573DW is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the 74F logic series. It features eight non-inverting D-type latches with tri-state outputs in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 8.6 ns at 5 V. It provides a low-level output current of 24 mA and a high-level output current of -3 mA. The component is rated for operation between 0°C and +70°C.

Feature Summary

• Octal transparent D-type latch configuration with tri-state outputs
• High-speed switching performance characteristic of the 74F logic family
• Non-inverting data path with dedicated latch enable control

Applications

• Registering data in high-speed digital systems
• Bus-oriented memory mapping applications
• Temporary storage of parallel data streams

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact pinout and electrical characteristics defined in the SN74F573 datasheet.

Selection Notes

Select this component when high-speed latching is required within standard 5V logic environments. The 74F series offers faster propagation delays compared to LS or ALS variants but consumes more power. Verify that the 24 mA sink capability meets the load requirements of the connected circuitry.

Part Context

This part belongs to the SN74F573 family of octal latches. It serves as a high-speed alternative to slower logic families like SN74LS373. The DW suffix indicates a 20-lead Small Outline Integrated Circuit (SOIC) package suitable for surface-mount technology applications.
