Description
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* IsoLoop 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 edge-
triggered inputs improve noise performance.

Notes:
1. Absolute Maximum specifications mean the device will not be damaged if operated under these conditions. It does not guarantee performance.
2. All voltages are with respect to network ground except differential I/O bus voltages.
3. The TxD input is edge sensitive. Voltage magnitude of the input signal is specified, but edge rate specifications must also be met.
4. The maximum time allowed for a logic transition at the TxD input is 1
μs.
