MC74LCX373MEL

Latches Overview

The MC74LCX373MEL is a low-voltage CMOS octal transparent latch with 5 V-tolerant inputs and outputs. It operates from a 2.3 to 3.6 V supply and contains eight D-type latches with three-state outputs. The device features high impedance TTL compatible inputs that significantly reduce current loading, while TTL compatible outputs offer improved switching noise performance. A VI specification of 5.5 V allows the inputs to be safely driven from 5 V devices.

Latches Feature Summary

• Features 5 V tolerant I/Os for interface capability with 5 V TTL logic
• Supports live insertion and withdrawal operations
• Includes IOFF specification to guarantee high impedance when VCC equals 0 V
• Provides balanced output sink and source capability

Latches Applications

• Interface between 5 V TTL logic and low voltage CMOS systems
• Data storage in digital circuits requiring non-inverting octal latching
• Applications requiring support for live insertion and withdrawal

Latches Procurement Notes

Verify the specific package suffix associated with the MEL designation against official onsemi documentation to confirm physical dimensions and pinout compatibility. Confirm RoHS compliance status and check for any discontinued status notices or recommended new design alternatives provided by the manufacturer before finalizing procurement plans.

Latches Selection Notes

Select this component for designs requiring an octal latch with 5 V tolerance within a 2.3 to 3.6 V operating range. Ensure input drivers can handle the specified high impedance characteristics and verify that the system power requirements align with the near zero static supply current specifications across all logic states.

Latches Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices manufactured by onsemi. The series is characterized by high speed operation and low power consumption. The MC74LCX373 specifically provides octal transparency with three-state outputs, distinguishing it from standard latches without output enable controls.

Latches Replacement Considerations

Consult the datasheet ordering information table for direct replacements. Note that NLV prefix parts have been updated to include a -Q suffix for automotive qualification.
