SN74AHC573PWRG4

Overview

The SN74AHC573PWRG4 is an octal transparent D-type latch manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and utilizes CMOS logic technology. The device features eight non-inverting outputs housed in a TSSOP-20 package. Key electrical specifications include a propagation delay of 14.5 ns and 8.8 ns, static current of 4 uA, low-level output current of 32 mA, and high-level output current of -8 mA. It supports a wide operating temperature range from -40 C to +125 C.

Feature Summary

• Octal transparent D-type latch architecture with eight independent data channels
• Wide supply voltage operation ranging from 2 V to 5.5 V
• Extended industrial temperature capability up to +125 C
• High drive capability with low-level output current of 32 mA

Applications

• General-purpose digital data storage circuits
• Bus-oriented memory applications
• Register files for microcontroller systems
• Data buffering in communication interfaces

Procurement Notes

Verify the complete part number including the G4 suffix to ensure compliance with specific environmental standards. Confirm the TSSOP-20 package type matches the target PCB footprint. Check the datasheet for exact pinout configurations and electrical limits before integration. Ensure the supply voltage remains within the specified 2 V to 5.5 V range during operation.

Selection Notes

Select this component when an octal latch with wide voltage flexibility is required. The AHC series offers faster switching speeds compared to standard HC logic. Consider the TSSOP-20 package for surface-mount assembly constraints. Verify that the 32 mA output drive meets the load requirements of the connected circuitry.

Part Context

This device belongs to the SN74AHC573 family of octal D-type latches. It shares functional similarities with other members like the SN74AHC573QPWRG4Q1 but lacks automotive qualification. The G4 suffix indicates lead-free construction and RoHS compliance. It serves as a standard solution for parallel data latching in commercial electronics.

FAQ
