HIGH-SPEED DIFFERENTIAL I/O FAMILY
description
NUMBER OF
DEVICE _CHANNELS SHUTDOWN
The THS415x is one in a family of fully differential
input/differential output devices fabricated using
Texas Instruments’ state-of-the-art BiComI
complementary bipolar process.
The THS415x is made of a true fully-differential
signal path from input to output. This design leads
to an excellent common-mode noise rejection and
improved total harmonic distortion.
