MC74LVX573MG

Latches Overview

The MC74LVX573MG is an octal D-type latch with 3-state outputs manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 3.6 V and features inputs tolerant up to 5.5 V, enabling interface between 5.0 V and 3.0 V systems. The device provides high-speed performance with typical propagation delays of 6.4 ns at 3.3 V. It includes power-down protection on inputs, balanced propagation delays, and low noise characteristics. The component is available in SOIC-20 and TSSOP-20 packages.

Latches Feature Summary

• Features 5 V-tolerant inputs for interfacing 5.0 V systems with 3.0 V logic levels
• Provides 3-state outputs controlled by separate output enable and latch enable inputs
• Includes power-down protection on inputs to minimize quiescent current consumption

Latches Applications

• Data bus buffering applications
• Memory address latching
• I/O port expansion

Latches Procurement Notes

Verify the specific package suffix (DW or DT) required for your design, as the MG designation indicates a generic family member without specifying the exact physical footprint. Confirm RoHS compliance status and check for obsolescence notices directly from onsemi before finalizing procurement plans.

Latches Selection Notes

Select this component when an octal latch with 3-state capability is needed for low-voltage digital systems. Ensure input signals do not exceed the 5.5 V tolerance limit. Verify that the operating temperature range of -40 °C to +85 °C meets environmental requirements.

Latches Part Context

This part belongs to the LVX series of advanced high-speed CMOS logic devices. The LVX family is designed for low-power applications requiring fast switching speeds. The MC74LVX573 specifically functions as an octal transparent latch with tri-state outputs, distinct from flip-flops or buffers within the same logic family.

Latches Replacement Considerations

Direct substitutes include MC74LVX573DWR2G and MC74LVX573DTG. Verify pin compatibility and electrical specifications match before substitution.
