SN74AC573N

Latches Overview

The SN74AC573N is an octal D-type transparent latch manufactured by Texas Instruments, belonging to the 74AC logic series. It features eight independent D-type latches with three-state outputs housed in a 20-pin PDIP package. The device operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -40 °C to +85 °C. Key electrical specifications include a maximum propagation delay of 9.5 ns, a static current of 4 uA, and output drive capabilities of 24 mA for both low and high states.

Latches Feature Summary

• Provides tri-state outputs capable of directly driving buses or handling high capacitive and low-impedance loads.
• Features true operation logic with non-inverting polarity for straightforward data path integration.
• Supports through-hole mounting via a standard 20-pin PDIP configuration.

Latches Applications

• I/O port buffering
• Bidirectional bus drivers
• Working registers

Latches Procurement Notes

Verify the specific suffix 'N' corresponds to the PDIP-20 package variant when sourcing. Confirm RoHS compliance status as indicated in official documentation. Ensure the selected component matches the required 2V to 6V operating voltage range for your target application environment.

Latches Selection Notes

Select this component for designs requiring octal latching with tri-state control in through-hole layouts. Compare against SN74ACT573N if higher speed is needed at 5V only, or SN74AHC573 variants for different packaging options. Verify that the 2V minimum supply voltage aligns with system power rails.

Latches Part Context

This part belongs to the SN74AC573 family of octal D-type transparent latches. It shares functional similarities with other members like SN74AC573DWR but differs in physical package type. The AC series offers faster switching speeds compared to legacy HC/HCT counterparts while maintaining CMOS compatibility.

Latches Replacement Considerations

SN74ACT573N serves as a compatible alternative within the same package, though it requires a 4.5V to 5.5V supply range. SN74AC573DWR offers identical functionality in a surface-mount SOIC package.
