Package

The ISO7842DWR is packaged in a 28-pin TSSOP (Thin Shrink Small Outline Package). This type of package is designed for surface mounting and is known for its compact size, suitable for applications where space efficiency is crucial.

Pinout

The ISO7842DWR is an isolated high-speed digital isolator with a total of 16 pins. Its primary function is to provide galvanic isolation between different parts of a circuit, which helps in protecting sensitive components from high voltages and noise, while allowing for high-speed data communication.
The pin configuration includes:
1. VDD1 (Pin 1) - Supply voltage for the input side.
2. GND1 (Pin 2) - Ground for the input side.
3. DI1 (Pin 3) - Data input for channel 1.
4. DO1 (Pin 4) - Data output for channel 1.
5. DI2 (Pin 5) - Data input for channel 2.
6. DO2 (Pin 6) - Data output for channel 2.
7. VDD2 (Pin 7) - Supply voltage for the output side.
8. GND2 (Pin 8) - Ground for the output side.
9. (Pins 9-16) - Additional pins used for internal functions and thermal management.
This device supports reliable data transfer with low power consumption and high isolation voltage ratings.
