TRIPLE DIFFERENTIAL LINE DRIVER

Rev A1, Page 2/6
DESCRIPTION
The iC-HE is a three channel line driver with comple-
mentary outputs optimized for line impedances in the
range of 75 Ω.
The push-pull output stages can deliver at least
200 mA from 24 V supply and are short-circuit-proof
and current-limited, shutting down with excessive
temperature or undervoltage conditon.
The emitter and collector outputs of an on-chip NPN
transitor is available for driving an external light emit-
ting diode. The base of the transistor is connected to
an internal reference voltage of 2.5 V. Collector cur-
rent at pin LED can be controlled by the value of the
resistor connected between ISET and ground.
The device is protected against ESD.
All inputs are compatible with CMOS and TTL levels.
