SN74LV573ARGYRG4

Latches Overview

The SN74LV573ARGYRG4 is an octal transparent D-type latch manufactured by Texas Instruments, featuring three-state outputs. It operates within a supply voltage range of 2 V to 5.5 V and supports an operating temperature range from -40°C to +85°C. The device utilizes a 20-pin VQFN package. Propagation delays are specified at 18.7 ns at 2.5 V, 14.5 ns at 3.3 V, and 8.8 ns at 5 V. Static current consumption is typically 20 uA. Output drive capabilities include a low-level output current of 32 mA and a high-level output current of -16 mA.

Latches Feature Summary

• Provides eight independent transparent D-type latches with shared latch enable and output enable controls.
• Features three-state outputs that allow direct interface with bus systems without additional buffer circuits.
• Designed for low-voltage applications with wide supply voltage compatibility ranging from 2 V to 5.5 V.

Latches Applications

• Parallel-to-serial data conversion in communication interfaces
• Bus-oriented memory address latching
• I/O port expansion for microcontroller systems

Latches Procurement Notes

Verify the specific suffix 'G4' indicates lead-free status and RoHS compliance as per manufacturer documentation. Confirm the 'R' suffix corresponds to the reel packaging format and the 'Y' suffix denotes the VQFN package type. Ensure the component matches the exact part number SN74LV573ARGYRG4 to guarantee correct electrical characteristics and pinout configuration for your design.

Latches Selection Notes

Select this component when designing systems requiring octal latching with three-state bus interfacing capabilities. It is suitable for applications needing operation across a wide voltage range of 2 V to 5.5 V. Consider the VQFN package for space-constrained designs. Verify that the propagation delay specifications meet the timing requirements of your specific logic family and clock speeds.

Latches Part Context

This component belongs to the SN74LV573A series of octal transparent D-type latches with three-state outputs. It is part of Texas Instruments' LV (Low Voltage) logic family, designed for low-power consumption and compatibility with various digital logic standards. The G4 suffix typically denotes a lead-free and RoHS-compliant version of the standard SN74LV573ARGYR part.

Latches Replacement Considerations

SN74LV573ARGYR is the non-green variant of this component. SN74LV573ADBR and SN74LV573APWRG4 are alternative packages within the same logical family but differ in physical footprint and pin arrangement. Verify pin compatibility before substitution.
