Introduction

The IL41050TT is a galvanically isolated, CAN (Controller Area Network) transceiver containing basic functions but without “S” or Vref pins. It is a direct replacement for the Texas Instruments ISO1050DW with much better reliability and longer barrier life, less EMI emissions, and true 8 mm external creepage. The IL41050 family provides isolated differential transmit capability to the bus and isolated differential receive capability to the CAN controller via NVE’s patented spintronic Giant Magnetoresistance (GMR) technology. A unique ceramic/polymer composite barrier provides excellent isolation and virtually unlimited barrier life. Designed for harsh CAN and DeviceNet environments, IL41050 transceivers have transmit data dominant time-out, bus pin transient protection, a rugged Charged Device Model ESD rating, thermal shutdown protection, and short-circuit protection. Unique edgetriggered inputs improve noise performance.
