MC74LCX07D

Overview

The MC74LCX07D is a hex buffer and line driver 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 2 V to 5.5 V. Key electrical parameters include a maximum propagation delay of 3.7 ns at 50 pF load, with output drive capabilities of -8 mA for high level and 8 mA for low level. It supports TTL input levels and functions across an operating 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 bus-oriented applications
• Compatible with TTL input logic levels for mixed-voltage interfacing

Applications

• Memory address buffering for data storage systems
• Clock distribution and timing signal driving
• Bus driver interfaces for communication protocols

Procurement Notes

Verify the specific suffix 'D' corresponds to the SOIC-14 package variant when sourcing. Confirm RoHS compliance status as manufacturing practices may vary by production batch. Ensure the supplier provides official datasheets matching the MC74LCX07D part number to validate pinout and electrical characteristics against design requirements.

Selection Notes

Select this component when designing circuits requiring multiple non-inverting buffers with open-drain outputs. It is appropriate for systems needing interface between different voltage domains, specifically where TTL inputs must drive lower voltage CMOS loads. Consider the 14-pin SOIC footprint for PCB layout constraints and verify that the open-drain nature aligns with the pull-up resistor requirements of the target application.

Part Context

This component is part of the 74LCX07 series, which offers high-speed performance with low power consumption typical of the LCX family. It serves as a fundamental building block for digital logic designs requiring signal isolation or level shifting. The device complements other LCX logic gates by providing robust driving capability for buses and memory lines.

Replacement Considerations

Check for direct equivalents such as MC74LCX07DR2G or MC74LCX07DG depending on packaging preferences (tape & reel vs. tube). Verify pin compatibility before substitution to ensure seamless integration into existing footprints.
