IC-VX: Monolithic 3-channel line driver, adjustable driver current: 30 mA (PROG pin open)/100 mA (PROG pin to VSUB)
IC-WE: Special 3-channel / 75 W line driver, integrated adapter for 75 W surge impedance, short switching times/high slew-rate, inverting/non-inverting operation selectable, RS422-compatible in push-pull switching, short-circuit-proof open collector output for error signalling in event of excess temperature or undervoltage
IC-DL: 3-channel differential line driver with integrated wave adaptation
