MC74LVX373MG

Latches Overview

The MC74LVX373MG 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 balanced propagation delays and low noise characteristics. Key electrical parameters include a maximum quiescent supply current of 40 µA at 3.6 V and a typical propagation delay of 5.8 ns at 3.3 V. It supports operating temperatures from -40°C to +85°C.

Latches Feature Summary

• Features 5V-tolerant inputs allowing direct interfacing between 5.0 V and 3.0 V logic systems.
• Provides high-speed operation with balanced propagation delays for efficient data latching.
• Includes power-down protection on inputs to prevent excessive current draw during standby.
• Offers robust ESD performance exceeding 2000 V via Human Body Model standards.

Latches Applications

• Data storage in digital communication systems
• Bus-oriented memory applications
• Clocked memory registers
• Translating buffers between different voltage domains

Latches Procurement Notes

Verify the specific package suffix required for your design, as the datasheet lists SOIC-20 (DW) and TSSOP-20 (DT) variants. Confirm RoHS compliance and lead-free status through official documentation. Ensure input voltages do not exceed the absolute maximum ratings to maintain reliability. Check for moisture sensitivity levels if using surface-mount packages.

Latches Selection Notes

Select this component when an octal latch with 3-state outputs is needed for bus-driven applications. It is suitable for designs requiring voltage translation between 5V and 3.3V domains due to its 5V-tolerant inputs. Consider the low power dissipation and high-speed performance for battery-operated or high-frequency digital circuits. Ensure the chosen package variant matches the PCB footprint requirements.

Latches Part Context

This part belongs to the MC74LVX373 series of advanced high-speed CMOS logic devices. It is designed for low-voltage applications and offers compatibility with standard logic families while providing improved performance metrics such as lower power consumption and higher speed compared to older technologies.

Latches Replacement Considerations

Check for pin-compatible alternatives within the same LVX family or other manufacturers' octal latches with 3-state outputs. Verify that substitute parts meet the 5V input tolerance requirement and operate within the 2.0 V to 3.6 V supply range. Ensure equivalent propagation delay and output drive capabilities are maintained.
