SN7406NG4

Overview

The SN7406NG4 is a hex inverter buffer and driver manufactured by Texas Instruments, belonging to the standard 7400 logic series. It features six independent inverters with open-collector high-voltage outputs capable of withstanding a minimum breakdown voltage of 30 V. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a low-level output current of 40 mA, a high-level output current of -250 uA, and a propagation delay of 23 ns at 5 V. It is housed in a 14-pin PDIP package and supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Provides six independent inverting buffers with open-collector outputs for high-voltage interfacing
• Capable of driving high-current loads such as lamps or relays due to 40 mA sink capability
• Input structures are compatible with standard TTL logic levels

Applications

• Interface between TTL logic circuits and MOS devices requiring higher voltage levels
• Driving indicator lights or small relay coils
• General-purpose inversion in digital logic systems

Procurement Notes

Verify that the specific order matches the SN7406NG4 designation, noting the 'N' suffix indicates the PDIP-14 through-hole package. Confirm RoHS compliance status via the manufacturer's official documentation, as environmental declarations can vary by production batch. Ensure the supplier provides valid traceability data for the component lot.

Selection Notes

Select this component when open-collector outputs with high-voltage tolerance are required for inverting signals. It is suitable for applications needing to drive loads beyond standard TTL capabilities, such as connecting to MOS inputs or low-power actuators. Compare against the non-G4 variant if lead-free manufacturing history is a strict requirement for the assembly process.

Part Context

This part belongs to the Texas Instruments SN7400 family of bipolar logic integrated circuits. It serves as a fundamental building block for digital systems, specifically designed to provide signal inversion and buffering. The device is functionally equivalent to other manufacturers' 7406 parts but adheres to TI's specific pinout and electrical specifications.

Replacement Considerations

The SN7406N is the direct predecessor without the Green (RoHS) suffix. Cross-reference with SN74LS06 for lower power consumption requirements, though note the different logic family characteristics.
