SN74AS573AN

Overview

The SN74AS573AN is an octal D-type flip-flop with three-state outputs manufactured by Texas Instruments. It belongs to the AS logic series and operates within a supply voltage range of 4.5 V to 5.5 V. The device features a propagation delay of 9 ns, with a low-level output current capability of 48 mA and a high-level output current of -15 mA. It is housed in a 20-pin PDIP package and supports through-hole mounting. The operational temperature range extends from 0 °C to +70 °C.

Feature Summary

• Octal D-type flip-flop architecture with three-state outputs
• High-speed AS logic series performance
• Strong drive capability for low-impedance loads

Applications

• Register storage applications
• Bus-oriented architectures
• Clock distribution circuits

Procurement Notes

Verify the specific suffix 'AN' corresponds to the standard 20-pin PDIP package when sourcing. Confirm that the operating environment remains within the specified 0 °C to +70 °C range. Ensure power supply stability between 4.5 V and 5.5 V to maintain the guaranteed 9 ns propagation delay. Check for RoHS compliance status as indicated in official documentation.

Selection Notes

Select this component when high-speed data latching is required alongside significant load driving capabilities. The AS series offers faster switching speeds compared to standard TTL or HC families. Consider the 20-pin DIP form factor for prototyping or legacy board designs requiring through-hole assembly methods.

Part Context

This part is part of the SN74AS573A family of octal flip-flops. It shares functional similarities with other octal registers but distinguishes itself through the advanced Schottky (AS) technology which provides superior speed and drive strength characteristics suitable for demanding digital systems.
