SN74LVT573DW

Latches Overview

The SN74LVT573DW is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the 74LVT logic series. It features eight D-type latches with three-state outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports a maximum data rate of 150 Mbps at 3.3 V. Key electrical parameters include a propagation delay of 2.9 ns at 3.3 V, low-level output current of 32 mA, and high-level output current of -32 mA. It functions as a level translator between 3.3-V and 5-V systems.

Latches Feature Summary

• Provides octal (8-bit) data storage with transparent latch operation when the latch-enable input is active.
• Features three-state outputs designed to drive high-capacitance or relatively low-impedance loads.
• Supports bidirectional bus architectures through controlled output states.

Latches Applications

• Implementing bidirectional bus drivers for system interconnects.
• Serving as buffer registers in digital signal processing paths.
• Functioning as I/O ports and working registers in microcontroller systems.

Latches Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and lead-free manufacturing details via the manufacturer datasheet. Ensure the ordering part number matches the required temperature range and packaging format for your assembly process.

Latches Selection Notes

Select this component for applications requiring 3.3-V to 5-V level translation with high-speed performance. Consider the 20-pin SOIC package constraints for PCB layout. Evaluate the 32 mA drive capability against load requirements. Compare against the SN74LVTH573 series if higher speed or different voltage compatibility is needed.

Latches Part Context

This component belongs to the Texas Instruments 74LVT family of low-voltage CMOS logic devices. It is functionally similar to the SN74ABT573 but optimized for lower voltage operation. The device is widely used in portable electronics and computing systems where power efficiency and speed are critical design factors.

Latches Replacement Considerations

Public confirmed substitutes include SN74LVTH573DW and SN74LVTH573DWR from Texas Instruments. Verify pinout compatibility and electrical characteristics before substitution.
