MC74LCX07M

Overview

The MC74LCX07M is a hex buffer manufactured by onsemi, belonging to the LCX logic family. It features six non-inverting channels with open-drain outputs in a 14-pin SOIC package. The device operates within a supply voltage range of 2V to 5.5V and supports TTL input levels. Key electrical characteristics include a maximum propagation delay of 3.7 ns at 50 pF load, with output drive capabilities of -8 mA high and 8 mA low. It functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides six independent non-inverting buffer channels for signal conditioning
• Features open-drain output configuration suitable for level shifting and wired-OR applications
• Compatible with TTL input logic levels while operating on CMOS supply voltages
• Designed for surface-mount installation in compact electronic assemblies

Applications

• Interface buffering between microcontrollers and peripheral devices
• Level translation circuits connecting different voltage domains
• Signal driving for open-collector bus architectures
• General-purpose logic buffering in consumer electronics

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm package type and tape/reel specifications. Confirm current production status as legacy variants may be obsolete. Ensure RoHS compliance requirements match project standards before procurement. Cross-reference ordering information with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when open-drain outputs are required for multiple buffered signals. Consider the LCX series for low power consumption and wide voltage operation. Evaluate package constraints to ensure the SOIC footprint fits the design layout. Verify that the open-drain nature aligns with downstream circuit pull-up requirements.

Part Context

This part belongs to the 74LCX07 family of hex buffers with open-drain outputs. It is distinct from the MC74LCX06 which provides inverting functionality. The MC74LCX07 variant offers non-inverting buffering, making it suitable for applications requiring signal preservation without phase inversion. It shares the LCX technology platform known for low static power consumption.

Replacement Considerations

Check for direct pin-compatible alternatives such as the MC74LCX07DR or MC74LCX07DTR2G from onsemi. Verify functional equivalence regarding open-drain outputs and voltage ranges. Consider cross-manufacturer equivalents like Fairchild's 74LCX07MTC if package compatibility allows.
