MAX319ESA+T from Analog Devices Inc Maxim Integrated, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | COM | passive | Analog-switch common terminal, which connects to NC or NO depending on the logic input. |
| 2 | NC | unconnected | Analog-switch normally closed terminal on the MAX319, conducting to COM when IN is at logic 0. |
| 3 | GND | power_in | Logic ground reference for the device. |
| 4 | V+ | power_in | Analog-signal positive supply input; the datasheet specifies single-supply operation from +10V to +30V or bipolar operation from ±4.5V to ±20V, with V+ to V- not to exceed 44V. |
| 5 | VL | power_in | Logic-level positive supply input, to be tied to +5V for TTL compatibility or to V+ for CMOS logic levels. |
| 6 | IN | input | Logic-level control input that selects the switch state, with VINL 0.8V maximum and VINH 2.4V minimum for the logic thresholds. |
| 7 | V- | power_in | Analog-signal negative supply input; tie to 0V for single-supply operation. |
| 8 | NO | passive | Analog-switch normally open terminal on the MAX319, conducting to COM when IN is at logic 1. |
