QUAD DIFFERENTIAL LINE DRIVER
Rev A5, Page 2/8
DESCRIPTION
iC-HD7 is a robust line driver for industrial 5 V and
24 V applications with four complementary output
channels.
For signal lines with a characteristic impedance of
30 to 140 Ω the integrated line adapter, optimized
to 75 Ω, minimizes ringing effects which arise when
there is no line termination.
cessive temperature.
For bus applications the driver stages can be
switched to high impedance by a high at input NEN.
The driver stage inputs have a Schmitt trigger char-
acteristic and are compatible with CMOS and TTL
levels.
At a supply of 24 V the push-pull driver stages typi-
cally provide 200 mA to discharge the line and also
have a low saturation voltage (of typically 200 mV
with a 40 mA low-side load). The outputs are current
limited and short-circuit-proof, shutting down with ex-
For test purposes the temperature monitor can be
deactivated by applying a voltage of greater than 12 V
to input NEN.
The device contains internal ESD protection circuitry.
