Product details

Six open-collector inverters for 5V logic and load driving

The SN7406DR is a hex inverter from the 7400 TTL family, each channel a single-input inverter with an open-collector output rated to sink 40 mA.

The open-collector output sinks 40 mA per channel.

14-SOIC, 3.90 mm body width. Standard footprint for reflow assembly.

Product status is Active, ROHS3 compliant. No end-of-life notice, no last-time-buy pressure.

Frequently asked questions

Is SN7406DR active or obsolete?

The SN7406DR is Active in production, ROHS3 compliant, and carries no end-of-life notice. No last-time-buy risk.

What is the output current of SN7406DR?

Each open-collector output can sink 40 mA. There is no specified high-level output current because the output floats high — an external pull-up resistor supplies the load current.
