Valid for logic state as described or open circuit DeviceNet X = dont care Description The IL41050TA is a galvanically isolated, CAN (Controller Area Network) transceiver, designed as the interface between the CAN protocol controller and the physical bus. The wide-body version provides true 8 mm creepage. Narrow-body and QSOP packages offer unprecedented miniaturization. The IL41050 family provides isolated differential transmit capability to the bus and isolated differential receive capability to the CAN controller via NVEs patented* IsoLoop spintronic Giant Magnetoresistance (GMR) technology. A unique ceramic/polymer composite barrier provides excellent isolation and virtually unlimited barrier life. Advanced features facilitate reliable bus operation. Unpowered nodes do not disturb the bus, and a unique non-volatile programmable power-up feature prevents unstable nodes. The devices also have a hardware-selectable silent mode that disables the transmitter. Designed for harsh CAN and DeviceNet environments, IL41050TA 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 edge- triggered inputs improve noise performance. IsoLoop is a registered trademark of NVE Corporation. REV. K *U.S. Patent number 5,831,426 6,300,617 and others.
