SN74AC573DWG4

Latches Overview

The SN74AC573DWG4 is an octal D-type transparent latch manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 2V to 6V. The device utilizes a 20-pin Small Outline Integrated Circuit (SOIC) package with a width of 7.50mm. It supports surface-mount installation and functions reliably across an operating temperature range from -40°C to +85°C. The component belongs to the AC logic series, providing non-inverting data transfer capabilities for digital circuit applications.

Latches Feature Summary

• Octal D-type transparent latch architecture with eight independent data paths
• Three-state output capability allowing direct bus-driven connections
• Wide power supply operation supporting voltages from 2V to 6V
• Industrial temperature rating ensuring stability in demanding environments

Latches Applications

• Parallel-to-serial data conversion interfaces
• Register banks for microprocessor systems
• Buffer memory storage in digital logic circuits
• Data acquisition system input latching

Latches Procurement Notes

Verify the G4 suffix indicates lead-free composition and RoHS compliance per manufacturer standards. Confirm the SOIC-20 package dimensions match PCB footprint requirements. Ensure the AC logic family specifications align with system voltage levels. Check for any specific handling instructions regarding moisture sensitivity during assembly processes.

Latches Selection Notes

Select this component when high-speed data latching is required with wide voltage flexibility. The AC series offers faster propagation delays compared to standard TTL equivalents. Consider the three-state outputs for shared bus architectures. Verify that the 20-pin SOIC package fits the available board space and thermal constraints of the final design.

Latches Part Context

This part is a lead-free, RoHS-compliant variant of the SN74AC573DWR. The G4 suffix denotes environmental compliance updates while maintaining identical electrical and functional characteristics. It belongs to the broader SN74AC573 family of octal latches designed for general-purpose digital logic applications requiring reliable data storage and transfer.

Latches Replacement Considerations

SN74AC573DWR serves as the primary equivalent without the environmental suffix. SN74AC573DWRE4 is another verified alternative within the same product line. Both maintain identical pinouts and performance metrics.
