Additional Details

The ATA6660-TAPY operates from a single 5V supply and is available in a small SOIC-8 package. It features a differential receiver with a wide common-mode range, ensuring reliable data reception even in the presence of noise. The transceiver also includes a transmit data (TXD) dominant timeout function, which prevents the CAN bus from being blocked by a faulty transmitter. This part also includes an extended temperature range, typically -40°C to +125°C, making it suitable for demanding automotive applications. The slew rate control is optimized to minimize electromagnetic emissions. The device is typically used with a microcontroller to implement a complete CAN node.
