MC74LCX07DTR2

Overview

The MC74LCX07DTR2 is a hex buffer and line driver manufactured by onsemi, belonging to the LCX logic series. It features six non-inverting buffers with open-drain outputs, designed for operation within a supply voltage range of 2V to 5.5V. The device utilizes a 14-pin SOIC surface-mount package and supports single-ended TTL input levels. Key electrical characteristics include a maximum propagation delay of 3.7 ns at 50 pF load, with high-level output current capability of -8 mA and low-level output current of 8 mA. It operates reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Provides six independent non-inverting buffer channels with open-drain output configuration
• Compatible with TTL input logic levels while operating on CMOS technology
• Supports wide supply voltage operation ranging from 2V to 5.5V

Applications

• Interface buffering between TTL and CMOS logic families
• Driving open-drain loads such as I2C buses or LED indicators
• Signal level translation in mixed-voltage digital systems

Procurement Notes

Verify the specific suffix 'DTR2' against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS directives if required for your application. Cross-reference the manufacturer part number with authorized distributors to confirm current production status and availability constraints.

Selection Notes

Select this component when multiple non-inverting buffers with open-drain outputs are required in a compact surface-mount form factor. The LCX series offers improved performance over legacy HC/HCT devices. Consider the 5.5V maximum rating and open-drain nature when designing pull-up resistor networks for the output lines.

Part Context

This component is part of onsemi's 74LCX family, which provides high-speed CMOS logic with low power consumption. The LCX series is designed to replace older 74HC and 74HCT devices in many applications, offering faster switching speeds and lower dynamic power dissipation while maintaining pin-out compatibility with standard logic packages.

Replacement Considerations

Check for direct substitutes like MC74LCX07DR2G or MC74LCX07DT depending on packaging requirements. Verify that any replacement maintains the open-drain output characteristic and compatible voltage ranges.
