MC74LCX07DR2

Overview

The MC74LCX07DR2 is a hex buffer manufactured by onsemi, belonging to the LCX logic series. It features six non-inverting channels with open-drain outputs in a 14-pin SOIC package. The device operates within a supply voltage range of 2 V to 5.5 V and supports TTL input levels. Key electrical parameters include a maximum propagation delay of 3.7 ns at 50 pF load, with output drive capabilities of -8 mA for high state and 8 mA for low state. It functions reliably across an industrial 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 bus driving and level shifting
• Compatible with TTL input logic levels for broad interface flexibility
• Operates over a wide supply voltage range from 2 V to 5.5 V

Applications

• Bus-oriented connections requiring open-drain termination
• Driving relays, lamps, or other high-current devices via open-drain outputs
• Level translation between different voltage domains
• General-purpose buffering for digital signals

Procurement Notes

Verify the specific suffix DR2 indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status as some listings indicate non-compliance while others suggest leaded content. Ensure the supplier provides official datasheets matching the MC74LCX07 family specifications. Check for any recent product change notices regarding packaging or material declarations before finalizing procurement.

Selection Notes

Select this component when open-drain outputs are required for wired-OR configurations or direct driving of loads exceeding standard CMOS limits. The LCX series offers low power consumption compared to older technologies. Ensure the application voltage does not exceed 5.5 V. Consider the 14-SOIC package constraints for PCB layout. Verify that the 3.7 ns delay meets timing requirements for the target frequency.

Part Context

This part belongs to the 74LCX07 family of hex buffers with open-drain outputs. It is part of onsemi's LCX line, designed for low-voltage applications. Similar parts include the MC74LCX07DG (tube packaging) and MC74LCX07DTR2G (TSSOP package). The LCX series is known for compatibility with 3.3 V systems while maintaining performance at higher voltages up to 5.5 V.

Replacement Considerations

MC74LCX07DG is a compatible alternative with identical electrical characteristics but differs in packaging, using tubes instead of tape-and-reel. MC74LCX07DTR2G offers the same functionality in a TSSOP-14 package. Verify pinout compatibility and thermal performance when substituting packages.
