iC-HX
3-CHANNEL DIFFERENTIAL COLD LINE DRIVER
Rev D1, Page 1/14
FEATURES
6 current-limited and short-circuit-proof push-pull drivers
Differential 3-channel operation selectable
Integrated impedance adaption for 30 to 140 lines
Wide power supply range from 4 to 40 V
200 mA output current (at VB = 24 V)
Low output saturation voltage (< 0.4 V at 30 mA)
Compatible with TIA/EIA standard RS-422
Tristate switching of outputs enables use in buses
Short switching times and high slew rates
Low static power dissipation
Dynamic power dissipation reduced with iC-xSwitch
Schmitt trigger inputs with pull-down resistors, TTL and CMOS
compatible; voltage-proof up to 40 V
Thermal shutdown with hysteresis
Error message trigger input TNER
Open-drain error output NER, active low with excessive chip
temperature and undervoltage at VCC or VB
Operating temperature range from -40 to 125 °C
APPLICATIONS
Line drivers for 24 V control
engineering
Linear scales and encoders
MR sensor systems
