SN7406DRIn StockTexas Instruments
The SN7406DR is a hex inverting buffer and driver with open-collector outputs from Texas Instruments, housed in the SOIC-14 surface-mount package. It contains six independent inverter/driver channels, each capable of sinking up to 40 mA at 30 V, making it ideal for driving TTL logic levels into higher-voltage loads such as relays, indicator lamps, and bus lines. The open-collector architecture enables wire-AND logic and direct interface to MOS and CMOS devices. Operating over the commercial temperature range of 0°C to 70°C, the SN7406DR is a compact and cost-effective solution for level shifting and load-driving applications in industrial and consumer electronics designs.

Frequently Asked Questions
What is the SN7406DR used for?
The SN7406DR is a hex inverting buffer and driver with open-collector outputs. It is commonly used for relay and solenoid driving, indicator lamp control, TTL-to-MOS/CMOS level shifting, and wire-AND bus interfacing applications.
What is the maximum output voltage and sink current for the SN7406DR?
The SN7406DR supports a maximum output voltage of 30 V and a maximum output sink current of 40 mA per channel, enabling it to directly drive higher-voltage loads beyond standard TTL levels.
What package does the SN7406DR come in?
The SN7406DR is available in a SOIC-14 (Small Outline Integrated Circuit, 14-pin) surface-mount package, making it suitable for compact PCB designs requiring automated assembly.
Is the SN7406DR RoHS compliant?
Yes, the SN7406DR is RoHS compliant and lead-free. Texas Instruments manufactures this device to meet international environmental standards for hazardous substances in electronic equipment.
What is the operating temperature range of the SN7406DR?
The SN7406DR operates over the commercial temperature range of 0°C to 70°C, making it suitable for standard indoor and industrial environments.
How many inverter channels does the SN7406DR contain?
The SN7406DR contains six (hex) independent inverter/driver channels in a single package, each with its own open-collector output for versatile multi-signal applications.
What is the difference between the SN7406DR and SN7407DR?
The SN7406DR is an inverting hex buffer/driver (output is the logical inverse of the input), whereas the SN7407DR is a non-inverting hex buffer/driver. Both feature open-collector outputs and the same electrical ratings, so the choice depends on whether signal inversion is required in your circuit.
