74LVT573MSAX

Latches Overview

The Fairchild Semiconductor 74LVT573MSAX is an octal transparent latch featuring three-state outputs, designed for bus-organized system applications. It operates within a supply voltage range of 2.0 V to 3.6 V. The device provides eight latches with non-inverting logic and includes an output enable function. It is housed in a 20-pin SSOP package.

Latches Feature Summary

• Octal transparent latch architecture with three-state outputs
• Compatible with low-voltage CMOS technology
• Designed for high-speed bus-oriented systems

Latches Applications

• Bus-oriented memory mapping
• I/O port circuits
• Register files

Latches Procurement Notes

This component is obsolete and no longer manufactured by Fairchild Semiconductor or ON Semiconductor. Sourcing requires checking secondary market distributors for existing stock. Verify the authenticity of available units and confirm the specific manufacturing date code, as these are end-of-life parts. Ensure compatibility with current design requirements before procurement.

Latches Selection Notes

Select this part only if legacy compatibility with the LVT series is required. Consider modern equivalents from other manufacturers if new designs allow. Verify that the SSOP-20 package fits the PCB layout constraints. Check if the 3.6 V maximum rating meets the system voltage requirements.

Latches Part Context

The 74LVT573MSAX belongs to the LVT (Low Voltage TTL) logic family, which bridges the performance gap between standard TTL and CMOS technologies. It offers faster switching speeds than LS series devices while maintaining lower power consumption. This specific variant is an octal latch with three-state outputs, commonly used in digital data storage and transfer applications.

Latches Replacement Considerations

Direct substitutes include SN74LVT573DBR from Texas Instruments. Other compatible parts may be found in the 74LVT573 series from various manufacturers, ensuring pinout and electrical specifications match.
