Package Type: SOIC-8 (Small Outline IC) Channels: 2 isolated channels (input/output) Operating Voltage Range: Typically 3.0V to 5.5V Data Rate: Up to 25 Mbps Temperature Range: -40°C to +125°C Isolation Voltage: 2500 Vrms Output Type: Digital (Open-Drain)Detailed Pin Functionality Description:
Pin 1 - VDD1: This pin supplies the positive voltage for the logic side of the device. It is typically connected to a 5V power supply. Ensure that this voltage is within the specified range (3.0V to 5.5V) for proper operation. Pin 2 - VSS1: This is the ground pin for the logic side (side 1). It should be connected to the system's ground to complete the electrical circuit. Pin 3 - IN1: This pin receives the input signal for isolation. It is the digital signal input for side 1. It could be a logic high (1) or logic low (0) based on the application. Pin 4 - IN2: This pin receives the input signal from side 2, similar to IN1 but for the other side of the isolator. Pin 5 - OUT1: This is the output of side 1. The signal on this pin is determined by the logic state of IN1 and the isolation function. This output may either be a logic high or low depending on the input signal. Pin 6 - OUT2: This is the output of side 2, serving the same function as OUT1 but for side 2. The output is derived based on the input signals from IN1 and IN2. Pin 7 - VDD2: This pin supplies the power for side 2 of the isolator. It is generally connected to the same voltage as VDD1, but the supply could vary depending on the specific circuit design. Pin 8 - VSS2: This pin serves as the ground for side 2 of the isolator. It should be connected to the system's ground.20 FAQ for ADUM1401BRWZ-RL:
