iC-HD7

QUAD DIFFERENTIAL LINE DRIVER

Rev A5, Page 1/8

FEATURES

o Complementary short-circuit-proof push-pull driver stages for

RS422 and 24 V applications up to 2 MHz

o Pin-compatible to 26LS31, xx7272

o Integrated line adaptation for high signal quality at 24 V

o Moderate slew rate reduces EMI

o High driving capability of typically 200 mA at 24 V

o Output saturation of just 0.3 V at 40 mAdc

o Tristate function for bus applications with excessive

temperature shutdown

o TTL-/CMOS-compatible Schmitt trigger inputs,

voltage-proof to 40 V

o 4.5 to 35 V single supply operation with low static power

dissipation

o Operating temperature from -25 to 125 °C (-40 °C is optional)

APPLICATIONS

o Line drivers for 24 V control

engineering

o Linear scales and encoders

o Sensor systems
