IC-DL_17 Datasheet, PDF (1/10 Pages) IC-Haus GmbH – 3-CHANNEL DIFFERENTIAL LINE DRIVER

iC-DL
3-CHANNEL DIFFERENTIAL LINE DRIVER
FEATURES
• 6 current-limited and short-circuit-proof push-pull drivers
• Differential 3-channel operation selectable
• Integrated impedance adaption for 30 to 140 Ω 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
• 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
• Option: Extended temperature range from -40 to 125 °C
