SN7406N-NG

Overview

The SN7406N is a hex inverter buffer/driver featuring open-collector high-voltage outputs. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range of 0°C to 70°C. The device provides a minimum breakdown voltage of 30 V on its outputs, with a maximum sink current capability of 40 mA. Propagation delay is characterized at 10 ns (min) to 23 ns (max) under standard test conditions.

Feature Summary

• Features open-collector outputs capable of interfacing with high-level circuits such as MOS logic or driving high-current loads like indicator lamps and relays.
• Includes input clamping diodes to simplify system design requirements.
• Inputs are fully compatible with most standard TTL circuit families.

Applications

• Converting TTL voltage levels to MOS logic levels
• Driving indicator lamps and relay coils
• Acting as inverter buffers for driving TTL inputs

Procurement Notes

Verify the specific ordering suffix 'N' corresponds to the PDIP-14 package configuration. Confirm that the required operating temperature range aligns with the commercial grade specification of 0°C to 70°C rather than the military grade variant. Ensure the application load does not exceed the 40 mA sink current limit or the 30 V output breakdown voltage rating.

Selection Notes

Select this component when high-voltage switching or high-current sinking is required from a standard TTL input source. The open-collector architecture allows for flexible output voltage levels determined by external pull-up networks. Consider the SN7416 if a lower 15 V breakdown voltage is sufficient, or the SN7407 if non-inverting functionality is needed instead.

Part Context

This part belongs to the SN5406/SN7406 family of hex inverter buffers/drivers. It is distinguished from the SN7416 by its higher 30 V output breakdown voltage compared to the 15 V rating of the SN7416. The 'N' suffix specifically denotes the plastic dual in-line package format suitable for through-hole mounting.

FAQ

What is the maximum voltage that can be applied to the outputs?

The SN7406 features a minimum breakdown voltage of 30 V on its open-collector outputs.

How does the SN7406 differ from the SN7416?

The primary difference is the output breakdown voltage; the SN7406 supports up to 30 V, whereas the SN7416 is rated for a maximum of 15 V.
