Package
The ISO7841DWWR is packaged in a TSSOP (Thin Shrink Small Outline Package) format, specifically a 16-pin TSSOP. This package type is designed for compact applications, providing a space-efficient solution for electronic circuits.
Pinout
The ISO7841DWWR is a digital isolator with a 16-pin count in the TSSOP package. This device features four independent channels for isolating digital signals, allowing for bidirectional data transfer. Each channel can support data rates up to 150 Mbps.
The pin functions include:
- VDD1 and VDD2: Power supply pins for the input and output sides, respectively.
- GND1 and GND2: Ground pins for the input and output sides.
- Channels (A1, B1, C1, D1): Input pins for the data, corresponding to the isolated output channels.
- Channels (A2, B2, C2, D2): Output pins that provide the isolated signals.
- Enable pins (OE1, OE2): Output enable pins that allow control of the output channels.
The ISO7841DWWR is designed for robust isolation, making it suitable for applications requiring high-speed data transfer across isolation barriers.
