DG445DY-E3

Vishay Intertech · Analog Switches, Multiplexers · SOIC-16

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).
