Important notice
Dear Customer,
On 7 February 2017 the former NXP Standard Product business became a new company with the
tradename
Nexperia.
Nexperia is an industry leading supplier of Discrete, Logic and PowerMOS
semiconductors with its focus on the automotive, industrial, computing, consumer and wearable
application markets
In data sheets and application notes which still contain NXP or Philips Semiconductors references, use
the references to Nexperia, as shown below.
Instead of http://www.nxp.com, http://www.philips.com/ or http://www.semiconductors.philips.com/,
use
http://www.nexperia.com
Instead of sales.addresses@www.nxp.com or sales.addresses@www.semiconductors.philips.com, use
