MC74LCX07MEL

Overview

The MC74LCX07MEL is a hex buffer manufactured by onsemi, belonging to the LCX logic series. It features six non-inverting elements with open-drain outputs in a 14-SOEIAJ package. The device operates within a supply voltage range of 2V to 5.5V and supports TTL input types. Key electrical parameters include a maximum low-level output current of 24mA and a high-level output current of -24mA. The propagation delay is specified at 3.7 ns under a 50 pF load condition. It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides six independent non-inverting buffer channels for signal conditioning
• Features open-drain output configuration suitable for wired-OR applications
• Compatible with TTL input logic levels for versatile interfacing
• Operates across a wide 2V to 5.5V power supply range

Applications

• Open-drain bus line drivers
• TTL-to-CMV level translation buffers
• General-purpose signal buffering in low-voltage systems

Procurement Notes

Verify the specific suffix MEL against official onsemi documentation to confirm the SOEIAJ-14 package type and pinout compatibility. Confirm RoHS compliance status as manufacturing updates may affect environmental declarations. Ensure the part number matches the exact ordering code required for your bill of materials, as variations exist within the LCX family.

Selection Notes

Select this component when designing circuits requiring open-drain outputs for bus sharing or voltage level shifting between different logic families. The LCX series offers low power consumption compared to older technologies. Verify that the system's maximum voltage does not exceed the absolute maximum ratings for both supply and input pins to prevent device damage.

Part Context

This component is part of the 74LCX07 family of hex buffers. While other variants like MC74LCX07DG use SOIC packages and MC74LCX07DT use TSSOP, the MC74LCX07MEL specifically utilizes the small outline external leadless (SOEIAJ) package. This family is designed for high-speed CMOS applications requiring low power dissipation.

Replacement Considerations

Direct substitutes include MC74LCX07DG and MC74LCX07DR2G, though these utilize SOIC packages rather than SOEIAJ. Cross-package replacements require careful review of footprint dimensions and pin spacing differences during PCB layout adaptation.
