Texas Instruments · Inverters · SOIC-14

SN7406DR from Texas Instruments, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1A input TTL-compatible input to inverter buffer/driver 1; internal input clamping diode limits negative excursions (VIK = -1.5 V at II = -12 mA).
2 1Y output Open-collector output of inverter buffer/driver 1 (Y = A'), rated for external pull-up voltages up to 30 V and able to sink up to 40 mA (IOL) for driving lamps, relays, or MOS-level loads.
3 2A input TTL-compatible input to inverter buffer/driver 2; internal input clamping diode limits negative excursions (VIK = -1.5 V at II = -12 mA).
4 2Y output Open-collector output of inverter buffer/driver 2 (Y = A'), rated for external pull-up voltages up to 30 V and able to sink up to 40 mA (IOL) for driving lamps, relays, or MOS-level loads.
5 3A input TTL-compatible input to inverter buffer/driver 3; internal input clamping diode limits negative excursions (VIK = -1.5 V at II = -12 mA).
6 3Y output Open-collector output of inverter buffer/driver 3 (Y = A'), rated for external pull-up voltages up to 30 V and able to sink up to 40 mA (IOL) for driving lamps, relays, or MOS-level loads.
7 GND power_in Ground reference terminal for the device; all voltage levels are specified with respect to this network ground.
8 4Y output Open-collector output of inverter buffer/driver 4 (Y = A'), rated for external pull-up voltages up to 30 V and able to sink up to 40 mA (IOL) for driving lamps, relays, or MOS-level loads.
9 4A input TTL-compatible input to inverter buffer/driver 4; internal input clamping diode limits negative excursions (VIK = -1.5 V at II = -12 mA).
10 5Y output Open-collector output of inverter buffer/driver 5 (Y = A'), rated for external pull-up voltages up to 30 V and able to sink up to 40 mA (IOL) for driving lamps, relays, or MOS-level loads.
11 5A input TTL-compatible input to inverter buffer/driver 5; internal input clamping diode limits negative excursions (VIK = -1.5 V at II = -12 mA).
12 6Y output Open-collector output of inverter buffer/driver 6 (Y = A'), rated for external pull-up voltages up to 30 V and able to sink up to 40 mA (IOL) for driving lamps, relays, or MOS-level loads.
13 6A input TTL-compatible input to inverter buffer/driver 6; internal input clamping diode limits negative excursions (VIK = -1.5 V at II = -12 mA).
14 VCC power_in Positive supply voltage pin, recommended operating range 4.75 V to 5.25 V (absolute maximum 7 V) for the SN7406.
