74LCX07YMTR

Overview

The STMicroelectronics 74LCX07YMTR is a low-voltage CMOS open drain hex buffer manufactured using sub-micron silicon gate and double-layer metal wiring C2MOS technology. It operates within a supply voltage range of 2.0 V to 3.6 V, with a maximum propagation delay of 5.2 ns at VCC = 3 V. The device features six inputs and six outputs in an SOIC-14 package, supporting surface mount installation. It includes power-down protection on inputs and outputs, symmetrical output impedance with minimum drive currents of 24 mA at VCC = 3 V, and meets AEC-Q100 automotive qualification standards.

Feature Summary

• Provides high-speed buffering for 3.3 V applications while maintaining compatibility with 5 V signal environments through tolerant inputs.
• Features open drain outputs suitable for bus-oriented connections and mixed-voltage system interfacing.
• Includes internal protection circuits against static discharge and transient excess voltage for enhanced reliability.

Applications

• Low-power and high-speed 3.3 V digital logic buffering
• Interfacing between 5 V signal environments and lower voltage logic circuits
• Bus-oriented driving in mixed-voltage systems

Procurement Notes

Verify the specific suffix YMTR corresponds to the SOIC-14 tape and reel packaging configuration. Confirm that the AEC-Q100 automotive grade qualification aligns with your project requirements. Ensure the open drain output type matches your circuit design needs, as it differs from standard push-pull buffers. Cross-reference the manufacturer part number with official datasheets to confirm pinout and electrical specifications before integration.

Selection Notes

Select this component when designing systems requiring interface between 5 V tolerant inputs and 3.3 V logic levels. The open drain architecture is essential for wired-OR configurations or level shifting applications. Consider the 5.2 ns propagation delay for timing-critical paths. Verify that the SOIC-14 package fits your PCB layout constraints and that the automotive grade rating satisfies environmental operating conditions.

Part Context

This component belongs to the 74LCX series of low-voltage CMOS logic devices. It serves as a hex buffer variant within the broader 74xx family, specifically optimized for modern low-voltage digital applications. The YMTR designation indicates a specific manufacturing lot and packaging format handled by STMicroelectronics.

Replacement Considerations

Direct substitutes include other manufacturers' 74LCX07 variants in SOIC-14 packages. Verify pin compatibility and electrical parameters such as propagation delay and drive current when considering alternatives from different vendors.
