iC-HD7
QUAD DIFFERENTIAL LINE DRIVER
Rev A6, 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.
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-
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.
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.
