74LCX07MTR

Overview

The 74LCX07MTR is a low-voltage CMOS hex buffer with open-drain outputs and 5 V tolerant inputs, 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 and supports an operating temperature range from -40 °C to +85 °C. The device features high-speed performance with a maximum propagation delay of 5.2 ns at 3 V and symmetrical output impedance ensuring minimum currents of 24 mA at 3 V. It includes power-down protection on inputs and outputs, latch-up performance exceeding 500 mA per JESD 17, and ESD immunity rated at 2000 V HBM, 200 V MM, and 1000 V CDM.

Feature Summary

• Features 5 V tolerant inputs allowing interfacing with 5 V signal environments while operating at lower voltages.
• Provides high-speed operation with symmetrical output impedance for stable signal transmission.
• Includes power-down protection on both inputs and outputs to prevent excessive current draw during power-off states.

Applications

• Automotive systems
• Industrial equipment
• Computer peripherals
• Consumer electronics

Procurement Notes

Verify the specific ordering code matches the required package type and temperature grade. Confirm that the automotive grade designation (YMTR) aligns with AEC-Q100 qualification requirements if applicable to the design. Ensure the tape and reel packaging specifications meet the automated assembly line constraints. Cross-reference the datasheet revision date to confirm the latest electrical characteristics are utilized for final validation.

Selection Notes

Select this component when a hex buffer with open-drain outputs is required for level shifting between 3.3 V logic and 5 V tolerant interfaces. The device is suitable for applications demanding low power consumption combined with high-speed switching capabilities comparable to 5 V AC/ACT families. Consider the SO-14 package dimensions and pinout compatibility with existing 74 series 07 designs during the integration phase.

Part Context

This part belongs to the 74LCX family of low-voltage CMOS logic devices produced by STMicroelectronics. It serves as a direct functional replacement for standard 74 series 07 buffers but offers improved speed and lower power consumption at 3.3 V operation. The device is designed to provide robust noise immunity and stable output performance in mixed-voltage digital systems.

Replacement Considerations

The 74LCX07YMTR is the automotive-grade variant of the 74LCX07MTR, sharing identical pinouts and functions but qualified according to AEC-Q100 standards. Both parts utilize the SO-14 package and support the same operating voltage and temperature ranges. Designers requiring automotive reliability should substitute the MTR suffix with YMTR without altering circuit schematics.
