MC74LVX573DT

Latches Overview

The MC74LVX573DT is an octal D-type latch with 3-state outputs manufactured by onsemi. It features 5 V-tolerant inputs, allowing interface between 5.0 V and 3.0 V systems. The device operates within a supply voltage range of 2.0 V to 3.6 V and supports an operating temperature from -40 °C to +85 °C. Propagation delay (LE to O) is typically 6.4 ns at VCC = 3.3 V with CL = 15 pF. Quiescent supply current is maximized at 4 µA at 25 °C. The component is housed in a TSSOP-20 package.

Latches Feature Summary

• Provides 5 V-tolerant inputs for interfacing 5.0 V systems with 3.0 V logic levels
• Features power down protection on inputs to prevent excessive current draw
• Offers balanced propagation delays and low noise characteristics

Latches Applications

• Interfacing 5.0 V systems to 3.0 V systems
• Octal data storage applications requiring transparent or latched modes
• High-speed digital signal processing circuits

Latches Procurement Notes

Verify the specific ordering suffix 'DT' corresponds to the TSSOP-20 package configuration as defined in the manufacturer's ordering information. Confirm that the procurement includes the Pb-Free designation and RoHS compliance status required for the application environment. Ensure the quantity matches the rail packaging specifications provided in the datasheet.

Latches Selection Notes

Select this component when an octal latch with 3-state outputs and 5 V-tolerant inputs is required. It is suitable for designs needing to bridge 5.0 V and 3.0 V logic domains. Consider the typical 6.4 ns propagation delay and low quiescent current for high-speed, low-power applications. Verify compatibility with the TSSOP-20 surface mount package constraints.

Latches Part Context

This part belongs to the MC74LVX573 series of advanced high-speed CMOS octal latches. It is functionally compatible with other standard logic families while offering improved performance metrics such as lower power dissipation and higher noise immunity. The series is designed for modern digital systems requiring reliable data storage and transfer capabilities.

Latches Replacement Considerations

Direct substitutes include MC74LVX573DWR2G and MC74LVX573DTR2G. These variants share identical electrical characteristics but differ in packaging and shipping quantities. The DWR2G uses SOIC-20, while DTR2G uses TSSOP-20 tape and reel packaging.
