MC74LCX07DTR2G

Overview

The MC74LCX07DTR2G is a hex buffer and line driver manufactured by onsemi, belonging to the LCX logic series. It features six non-inverting channels with open-drain outputs, designed for surface-mount applications in a 14-TSSOP package. The device operates within a supply voltage range of 2 V to 5.5 V, supporting both 2-V and 5-V CMOS logic families. Key electrical specifications include a maximum propagation delay of 3.7 ns at 50 pF load, with output drive capabilities of -8 mA high and 8 mA low. It functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides six independent non-inverting buffering channels for signal integrity maintenance.
• Features open-drain output configuration suitable for bus-oriented and wired-OR applications.
• Supports dual voltage operation compatible with 2-V and 5-V CMOS logic standards.

Applications

• Bus-oriented systems requiring level translation between different voltage domains
• Driving capacitive loads in digital communication interfaces
• General-purpose buffering for microcontroller I/O expansion

Procurement Notes

Verify the specific suffix DTR2G to confirm the TSSOP-14 package and tape-and-reel quantity. Ensure compatibility with 2-V to 5.5-V supply rails. Check RoHS compliance status as per current manufacturer documentation. Confirm lead times and obsolescence notices directly with onsemi or authorized distributors before finalizing procurement plans.

Selection Notes

Select this component when hex buffering with open-drain outputs is required for mixed-voltage environments. It serves as a direct replacement for legacy 74HC07 or 74HCT07 devices where lower power consumption and wider voltage tolerance are necessary. Consider the 3.7 ns propagation delay for timing-critical paths. Ensure the application does not require push-pull outputs, as this part is strictly open-drain.

Part Context

This device is part of onsemi's LCX family, which bridges the performance gap between standard HC/HCT logic and faster AC/ACT families while maintaining low power dissipation. The LCX series is optimized for portable and battery-operated applications due to its wide operating voltage range and reduced static power consumption compared to older CMOS technologies.

Replacement Considerations

MC74LCX07DR2G (SOIC-14 package variant). Verify pinout compatibility and package dimensions when substituting TSSOP with SOIC. Ensure thermal characteristics match the new footprint constraints.
