NVE IL41050TA Isolated CAN Transceivers
Beat TI on Size, Transient Immunity, EMI Emmissions, and Reliability
Texas Instruments might claim to have a similar part to the IL41050TA, but don’t be fooled. Key differences are summarized below:

Smaller
TI’s smallest package is a clunky, non-standard “DUB” package that sacrifices silent mode and reference pins,
is twice the height of NVE’s JEDEC-standard SOIC packages, and its large thermal mass is hard to solder. NVE’s elegant narrow SOIC
takes 40% less board area and is less than one-fourth the package volume.
Better Creepage
The unique NVE True 8 wide-body package guarantees 8 mm minimum creepage as defined under IEC 60601 rules, which is required for 250 working volts.
Whatever isolation voltage they claim, TI parts do not meet the standard after subtracting tie bars as required under agency standards, and do not meet
IEC 250 working volt requirements.
Better EMC Footprint
With no carriers or clocks, NVE isolators have orders of magnitude lower emissions.
TI’s capacitive coupling couples in noise for more EMI susceptibility. NVE’s
unique spintronic technology has unsurpassed EMI immunity.
Tougher
| • |
Precision manufacturing results in a minimum transient immunity of 30 kV/µs,
which is 20% better than TI.
|
| • |
The IL41050TA works over the full extended industrial temperature range, up to 125°C. TI comes up short.
|
| • |
A unique ceramic/polymer barrier gives NVE isolators a barrier life of 44000 years
at 1000 Vrms. TI’s oxide barrier has a working life specification of 25 years
and only 13 years at a barrier voltage of 800 Vrms.
|
| • |
1014 ohms isolation resistance, which is 100 times better than TI.
And TI’s isolation resistance decreases sharply with temperature.

Smarter
NVE is expert in isolators and CAN. Most TI support people aren’t familiar with CAN.
Distributors and customer can call our applications hotline (800-GMR-7141 ext. 4) or e-mail our applications desk (iso-apps@nve.com) to get a CAN expert without getting bounced around.
