DG445DY-E3 from Vishay Intertech, in a SOIC-16. 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 | IN1 | input | Digital control input for switch 1; logic thresholds are 0.8 V (logic 0) and 2.4 V (logic 1), and on the DG445 a logic 1 turns the switch on (inverse of DG444 truth table). |
| 2 | D1 | passive | Drain terminal of switch 1; signals on D1 exceeding V+ or V- are clamped by internal diodes, so forward diode current must be limited to the maximum current ratings. |
| 3 | S1 | passive | Source terminal of switch 1; signals on S1 exceeding V+ or V- are clamped by internal diodes, so forward diode current must be limited to the maximum current ratings. |
| 4 | V- | power_in | Negative power supply; absolute maximum V+ to V- is 44 V, and dual supplies of ±5 V to ±20 V are supported. |
| 5 | GND | power_in | Ground reference; absolute maximum GND to V- is 25 V. |
| 6 | S4 | passive | Source terminal of switch 4; signals on S4 exceeding V+ or V- are clamped by internal diodes, so forward diode current must be limited to the maximum current ratings. |
| 7 | D4 | passive | Drain terminal of switch 4; signals on D4 exceeding V+ or V- are clamped by internal diodes, so forward diode current must be limited to the maximum current ratings. |
| 8 | IN4 | input | Digital control input for switch 4; logic thresholds are 0.8 V (logic 0) and 2.4 V (logic 1), and on the DG445 a logic 1 turns the switch on (inverse of DG444 truth table). |
| 9 | IN3 | input | Digital control input for switch 3; logic thresholds are 0.8 V (logic 0) and 2.4 V (logic 1), and on the DG445 a logic 1 turns the switch on (inverse of DG444 truth table). |
| 10 | D3 | passive | Drain terminal of switch 3; signals on D3 exceeding V+ or V- are clamped by internal diodes, so forward diode current must be limited to the maximum current ratings. |
| 11 | S3 | passive | Source terminal of switch 3; signals on S3 exceeding V+ or V- are clamped by internal diodes, so forward diode current must be limited to the maximum current ratings. |
| 12 | VL | power_in | Logic supply input; absolute maximum range is (GND - 0.3) V to (V+) + 0.3 V, and the datasheet tests with VL = 5 V. |
| 13 | V+ | power_in | Positive power supply; single-supply range is +5 V to 36 V, and absolute maximum V+ to V- is 44 V. |
| 14 | S2 | passive | Source terminal of switch 2; signals on S2 exceeding V+ or V- are clamped by internal diodes, so forward diode current must be limited to the maximum current ratings. |
| 15 | D2 | passive | Drain terminal of switch 2; signals on D2 exceeding V+ or V- are clamped by internal diodes, so forward diode current must be limited to the maximum current ratings. |
| 16 | IN2 | input | Digital control input for switch 2; logic thresholds are 0.8 V (logic 0) and 2.4 V (logic 1), and on the DG445 a logic 1 turns the switch on (inverse of DG444 truth table). |
