SN7406DRG4

Overview

The SN7406DRG4 is a hex inverter buffer and line driver from the Texas Instruments 7400 logic series. It features six independent inverters with open-collector outputs capable of driving high-voltage loads up to 35 V. The device operates within a supply voltage range of 4.75 V to 5.25 V, drawing a maximum quiescent current of 51 uA. It is housed in a surface-mount SOIC-14 package and supports propagation delays of 23 ns at 5 V. The component functions as an inverting buffer, providing signal inversion and level shifting for digital circuits.

Feature Summary

• Hex inverter configuration with six independent channels
• Open-collector output structure for high-voltage load driving
• Inverting logic polarity for signal phase reversal
• Surface-mount packaging for automated assembly

Applications

• High-voltage indicator circuits
• Relay driver interfaces
• Line termination applications
• Switch-mode power supply control loops

Procurement Notes

Verify the specific suffix G4 indicates lead-free and RoHS compliance status according to manufacturer documentation. Confirm the SOIC-14 package dimensions match PCB footprint requirements. Ensure operating conditions remain within the specified 4.75 V to 5.25 V supply range to maintain electrical characteristics. Check for any environmental certifications required by the end application standards.

Selection Notes

Select this component when open-collector outputs are required for interfacing with higher voltage domains than the logic supply. The 7400 series offers robust performance for standard digital applications. Consider the SOIC-14 package size for space-constrained designs. Verify that the 35 V output rating meets the load voltage requirements of the target circuit.

Part Context

This part belongs to the SN7406 family of hex inverters with open-collector outputs. It is functionally equivalent to other variants such as SN7406D or SN7406N, differing primarily in packaging and manufacturing revisions. The DRG4 designation specifies the tape-and-reel surface-mount format with green molding compound and halogen-free materials.
