SN74AC573QPWRQ1

Overview

The SN74AC573QPWRQ1 is an automotive-grade octal transparent D-type latch with three-state outputs. It operates within a supply voltage range of 1.5V to 6V and supports a temperature range of -40°C to +125°C. The device features balanced CMOS outputs capable of continuous ±24mA drive at 5V, with short bursts up to ±75mA. Maximum propagation delay is 7.9ns at 5V with a 50pF load. Inputs accept voltages up to 6V, and the package is TSSOP-20.

Feature Summary

• AEC-Q100 qualified for automotive applications
• Wide operating voltage range from 1.5V to 6V
• Balanced CMOS three-state outputs for bus driving
• High-speed data transfer with low propagation delay

Applications

• Parallel data storage
• Digital bus buffer

Procurement Notes

Verify the specific ordering suffix matches the required package type and tape/reel configuration. Confirm that the component meets AEC-Q100 Grade 1 requirements for your target environment. Ensure input signals do not exceed absolute maximum ratings to prevent damage. Check thermal resistance values if high switching frequencies are expected.

Selection Notes

Select this component when an octal latch with three-state capability is required in automotive environments. It is suitable for systems needing wide voltage compatibility between 1.5V and 6V. Consider its drive strength for direct transmission line interfacing. Verify that the TSSOP-20 package fits the available PCB space.
