SN74HCT573DWRG4

Latches Overview

The SN74HCT573DWRG4 is an octal transparent D-type latch manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features non-inverting outputs with three-state capability. The device provides low-level output current of 32 mA and high-level output current of -6 mA. Propagation delay is specified at 52 ns at 4.5 V and 47 ns at 5.5 V, with a static current consumption of 8 uA. It functions reliably across an operating temperature range from -40°C to +85°C.

Latches Feature Summary

• Octal transparent D-type latch architecture with eight independent data paths
• Three-state outputs enabling direct bus driving connections
• Non-inverting logic polarity for straightforward signal transmission

Latches Applications

• Parallel-to-serial data conversion circuits
• Bus-oriented memory address latching
• Register file storage elements in digital systems

Latches Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and manufacturing lot details. Confirm package type matches SOIC-20 requirements. Check for obsolescence status as this component may be discontinued. Ensure voltage levels align with system specifications before integration.

Latches Selection Notes

Select this component when interfacing between HCT logic families requiring octal latching. Compare propagation delays against HC series alternatives if lower power is needed. Verify package dimensions fit PCB layout constraints. Consider thermal performance within the specified operating temperature range.

Latches Part Context

This part belongs to the SN74HCT573 family of octal latches. It shares functional similarities with other HCT series devices but offers specific electrical characteristics suited for 5V logic applications. The device integrates standard latch functionality with enhanced drive capabilities typical of the HCT technology node.

Latches Replacement Considerations

SN74HCT573DWR is a compatible alternative without the G4 suffix. SN74HCT573DBR offers SSOP packaging instead of SOIC. SN74HC573ADWRG4 provides HC series performance with different voltage ranges.
