SN74AC573NS

Latches Overview

The SN74AC573NS is an octal D-type transparent latch with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and accepts input voltages up to 6V. The device features a maximum propagation delay of 9ns at 5V. It utilizes a 20-pin Small Outline (NS) package. Electrical characteristics include low-level output currents of 12mA at 3V and 24mA at 4.5V or 5.5V, with corresponding high-level output currents of -12mA and -24mA respectively. Static current is specified at 4μA maximum at 5.5V.

Latches Feature Summary

• Features 3-state outputs designed for driving bus lines directly without interface components.
• Capable of driving highly capacitive or relatively low-impedance loads effectively.
• Inputs accept voltages up to the maximum supply voltage rating.

Latches Applications

• Buffer registers
• Bidirectional bus drivers
• Working registers

Latches Procurement Notes

Verify the specific ordering suffix 'NS' corresponds to the SOP package variant when sourcing. Confirm RoHS compliance status and lead finish details via the manufacturer's latest packaging addendum. Ensure the procurement channel provides valid traceability documentation consistent with production data requirements.

Latches Selection Notes

Select this component for designs requiring octal latching with tri-state capability in a surface-mount form factor. Consider the 2V to 6V operating range for flexibility across different logic families. Evaluate thermal resistance metrics if operating near temperature limits. Verify pin compatibility against existing PCB footprints for the 20-pin SOP configuration.

Latches Part Context

This part belongs to the SN74AC573 family of octal D-type transparent latches. The NS suffix designates the Small Outline package type. Other variants in the series include PDIP, SSOP, SOIC, TSSOP, and VQFN packages. Automotive qualified versions are available under the SN74AC573-Q1 designation.
