SN74LV573APWRG4

Latches Overview

The SN74LV573APWRG4 is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the LV logic series. It features eight non-inverting circuits housed in a TSSOP-20 surface-mount package. The device operates within a supply voltage range of 2 V to 5.5 V and supports an operating temperature from -40°C to +85°C. Key electrical parameters include a propagation delay of 18.7 ns at 2.5 V, 14.5 ns at 3.3 V, and 8.8 ns at 5 V. Static current is specified at 20 uA, with low-level output current of 32 mA and high-level output current of -16 mA.

Latches Feature Summary

• Provides tri-state octal D-type latching functionality for data storage applications
• Supports wide supply voltage operation ranging from 2 V to 5.5 V
• Features low static current consumption for power efficiency

Latches Applications

• Parallel-to-serial data conversion interfaces
• Memory address latching in embedded systems
• I/O port expansion for microcontrollers

Latches Procurement Notes

Verify the G4 suffix indicates RoHS compliance and green manufacturing options as per Texas Instruments standards. Confirm the TSSOP-20 package dimensions match your PCB footprint requirements. Ensure the operating temperature range of -40°C to +85°C meets your environmental specifications. Check that the 2 V to 5.5 V supply voltage range aligns with your system power rails.

Latches Selection Notes

Select this component when requiring an octal latch with tri-state outputs and wide voltage compatibility. The LV series offers lower power consumption compared to standard CMOS families while maintaining robust drive capabilities. Consider the TSSOP-20 package for space-constrained designs. Verify signal integrity requirements against the specified propagation delays at your target supply voltage.

Latches Part Context

This part belongs to the SN74LV573A family of octal D-type latches. The G4 suffix typically denotes lead-free and RoHS-compliant construction. It shares functional similarities with other 74LV573 variants but differs in packaging and specific manufacturing revisions. The device is designed for general-purpose digital logic applications requiring reliable data latching.

Latches Replacement Considerations

SN74LV573ADBR (SSOP-20 package), SN74LV573ADWR (SOIC-20 package). Verify pinout compatibility and thermal characteristics before substitution.
