MC74LCX07MELG

Overview

The MC74LCX07MELG is a hex buffer manufactured by onsemi, belonging to the 74LCX logic series. It features six non-inverting elements with open-drain outputs and accepts TTL input levels. The device operates within a supply voltage range of 2V to 5.5V and supports surface-mount installation in a 14-SOEIAJ package. It provides high output drive capability with currents up to 24mA and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Hex configuration providing six independent non-inverting buffer channels
• Open-drain output architecture allowing flexible interfacing and level shifting
• TTL-compatible input thresholds for direct connection to legacy logic systems
• High current drive capability suitable for driving capacitive loads

Applications

• Interface circuits connecting 3.3V or 5V CMOS logic to open-drain peripherals
• Level translation between different voltage domains in mixed-signal designs
• Bus driver applications requiring high fan-out and signal buffering
• General-purpose digital signal conditioning in embedded systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and environmental compliance status. Confirm RoHS and lead-free status as manufacturing processes evolve. Check component availability and lifecycle status directly with authorized distributors before finalizing procurement plans.

Selection Notes

Select this component when a hex buffer with open-drain outputs is required for TTL-to-CMOS interfacing. Ensure the design accommodates the necessary pull-up resistors for the open-drain configuration. Verify that the operating voltage range aligns with the system power rails and that the package dimensions fit the PCB layout constraints.

Part Context

This part belongs to the 74LCX family of low-voltage CMOS logic devices. These components are designed to provide high-speed operation while maintaining low power consumption. The LCX series is widely used in portable electronics and battery-powered applications due to its wide operating voltage range and compatibility with standard logic families.

Replacement Considerations

Check for equivalent parts such as MC74LCX07DR2G or MC74LCX07DT. Verify pinout compatibility and electrical specifications before substitution. Note that some variants may have different packaging or obsolete status.
