Product details

Open-collector hex buffer for legacy bus and level-shift duties

The Texas Instruments SN7417N is a 7400-series hex non-inverting buffer with open-collector outputs, each rated to sink 40 mA. The open-collector stage lets you drive loads referenced to a higher voltage than VCC — common in 5 V to 12 V or 5 V to 24 V level shifting, relay and lamp drivers, and wired-OR bus structures where multiple outputs share a pull-up.

Why the 40 mA sink rating matters for your load budget

Each of the six buffers can sink 40 mA when the output is low, with no specified high-level drive current (the open collector floats high through an external pull-up resistor). The total package dissipation limits how many channels can sink full current simultaneously — at 5.25 V supply and all six outputs low at 40 mA each, the package dissipates roughly 1.26 W, which the PDIP handles with moderate airflow but not in a sealed enclosure without derating.

Pinout and package — what the 14-pin PDIP connects to

The SN7417N comes in a 14-pin PDIP (0.300" row spacing), socket-compatible with industry-standard DIP-14 layouts. Supply pins are VCC (pin 14) and GND (pin 7). The six buffer channels follow the conventional 7400-series pinout: inputs on pins 1, 3, 5, 9, 11, 13; corresponding open-collector outputs on pins 2, 4, 6, 8, 10, 12. No pinout detail beyond the footprint is carried in this listing — verify signal assignments against the official datasheet before layout.

Frequently asked questions

What does an open-collector output mean on the SN7417N?

An open-collector output can pull the line low (sink current) but cannot drive it high — an external pull-up resistor to a positive supply is required to establish the high state. This lets the output swing to a voltage higher than VCC (within the transistor breakdown limit), making it useful for level shifting and wired-OR connections.

Can the SN7417N be used as a level shifter?

Yes. Because the open-collector output floats when off, the pull-up resistor can be connected to a higher supply rail — for example, pull up to 12 V or 24 V while the input remains at 5 V logic levels. The output transistor must withstand the pull-up voltage; the SN7417N is rated for 30 V on the output when off, so it can shift 5 V logic to 12 V or 24 V loads.
