**Analog Devices Inc Maxim Integrated** · Interface - Specialized · SOIC-8

DS2482S-100+T&R from Analog Devices Inc Maxim Integrated, in a SOIC-8. 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 | VCC | power_in | Power-supply input with operating voltage range of 2.9V to 5.5V. |
| 2 | IO | bidirectional | 1-Wire input/output driver with selectable active or passive pullup, slew-rate control, and strong pullup capability for power delivery. |
| 3 | GND | power_in | Ground reference. |
| 4 | SCL | input | I2C serial clock input (0-400kHz) with Schmitt trigger; must be connected to VCC through a pullup resistor. |
| 5 | SDA | bidirectional | I2C serial data input/output (0-400kHz) with open-drain output and Schmitt trigger; must be connected to VCC through a pullup resistor. |
| 6 | PCTLZ | output | Active-low control output for external p-channel MOSFET with VOL=0.4V at 1.2mA and VOH=VCC−0.5V at 0.4mA load. |
| 7 | AD1 | input | I2C address input (connect to VCC or GND) determining bit A1 of the I2C slave address. |
| 8 | AD0 | input | I2C address input (connect to VCC or GND) determining bit A0 of the I2C slave address. |
