74LCX07SJX

Overview

The MC74LCX07SJX is a low-voltage CMOS hex buffer manufactured by onsemi, utilizing sub-micron silicon gate and double-layer metal wiring C2MOS technology. It features open-drain outputs and is designed for high-speed, low-power applications at 3.3 V. The device provides 5 V tolerant inputs, allowing interfacing with 5 V signal environments. It includes power-down protection on inputs and outputs, symmetrical output impedance, and ESD immunity of 2 kV HBM.

Feature Summary

• Low-voltage CMOS hex buffer with open-drain outputs
• 5 V tolerant inputs for mixed-signal interfacing
• Power-down protection on inputs and outputs
• High noise immunity with stable output circuitry

Applications

• Low-power and high-speed 3.3 V applications
• Interfacing 3.3 V logic to 5 V signal environments
• PCI bus level driving

Procurement Notes

Verify the manufacturer designation carefully, as the 'SJX' suffix is historically associated with Fairchild Semiconductor. Confirm if the specific part number corresponds to an onsemi product or a legacy Fairchild item, as sourcing channels may differ. Ensure the datasheet matches the exact pinout and electrical characteristics required for the design.

Selection Notes

Select this component when a non-inverting hex buffer with open-drain capability is required in a low-voltage environment. It is suitable for designs needing 5 V input tolerance while operating at lower supply voltages. Consider the package type and lead-free status during selection to match assembly requirements.

Part Context

This component belongs to the 74LCX series of low-voltage CMOS logic devices. The LCX family is known for combining the speed performance of the 5 V AC/ACT families with significantly lower power consumption. It is functionally compatible with standard 74 series logic but optimized for modern low-voltage systems.

Replacement Considerations

Check for direct equivalents from other manufacturers such as Nexperia or Texas Instruments that offer the same 74LCX07 specification in a SOIC-14 package. Verify pin compatibility and electrical parameters before substitution.
