SN74AHC573PWR

Overview

The SN74AHC573PWR is an octal transparent D-type latch manufactured by Texas Instruments, designed for operation within a voltage range of 2V to 5.5V. It features three-state outputs and operates in the AHC logic series. The device utilizes a TSSOP-20 surface-mount package. Key electrical characteristics include a maximum propagation delay of 14.5 ns at 5V and 8.8 ns at 3.3V. Static current consumption is specified at 4 uA. Output drive capabilities provide a low-level output current of 32 mA and a high-level output current of -8 mA. Operating temperatures span from -40°C to +85°C.

Feature Summary

• Transparent latch functionality where outputs follow data inputs when the latch enable signal is active.

Applications

• General-purpose digital data storage
• Bus driver applications requiring tri-state control

Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-20 package and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply chain sources are authorized distributors to guarantee component authenticity and traceability for production environments.

Selection Notes

Select this component for designs requiring wide voltage compatibility between 2V and 5.5V with moderate speed requirements. The TSSOP-20 package suits space-constrained printed circuit board layouts. Consider the 32 mA sink capability for direct driving of loads without additional buffering stages.

Part Context

This part belongs to the SN74AHC573 family of octal D-type latches. It shares functional similarities with other variants like the SN74HC573 but offers improved switching speeds due to the advanced CMOS technology. The PWR designation specifically identifies the plastic small-outline thin profile package variant.
