74LVT573MTC

Latches Overview

The Fairchild Semiconductor 74LVT573MTC is an octal transparent latch fabricated using advanced low-voltage CMOS technology. It features eight D-type latches with three-state outputs, designed for high-speed data storage and bus interfacing applications. The device operates within a supply voltage range of 2.7V to 3.6V and utilizes a 20-pin TSSOP package. Key electrical characteristics include a propagation delay of 4.4ns at 3.3V and output drive capabilities of 32mA for high-level and 64mA for low-level currents.

Latches Feature Summary

• Octal transparent latch architecture providing eight independent D-type memory elements
• Three-state outputs enabling direct connection to system buses without external drivers
• Advanced low-voltage CMOS process ensuring high noise immunity and low power consumption

Latches Applications

• High-speed data storage in digital communication systems
• Bus-oriented memory mapping and address decoding circuits
• Parallel-to-serial conversion interfaces in embedded controllers

Latches Procurement Notes

Verify the specific manufacturer source as this component has been associated with both Fairchild Semiconductor and onsemi due to corporate acquisitions. Confirm RoHS compliance status and check for End-of-Life notices or Production Change Notifications from current distributors. Ensure the package marking matches the required revision level for your design.

Latches Selection Notes

Select this component when designing low-voltage logic systems requiring octal latching with bus-compatible outputs. Compare against 74LVTH573 variants if higher drive strength or different voltage thresholds are needed. Verify that the 2.7V minimum supply voltage aligns with your system's power rails and that the TSSOP footprint fits your PCB layout constraints.

Latches Part Context

This part belongs to the 74LVT logic family, which provides low-voltage operation compatible with 3.3V systems while maintaining performance levels suitable for high-speed digital applications. The LVT series bridges the gap between standard LV and LVTH families, offering balanced speed and power characteristics for modern embedded designs.

Latches Replacement Considerations

Public confirmed substitutes include Nexperia 74LVT573PW and Texas Instruments SN74LVT573PWR. These alternatives maintain pin compatibility and functional equivalence but may differ in specific electrical parameters or packaging options.
