Description
iC-HX is a fast line driver with six independent channels
and integrated impedance adaptation for 30 to
140 Ω lines.
Channels are paired for differential 3-channel operation
by a high signal at the DIFF input, providing
differential output signals for the three inputs E1, E3
and E5. All inputs are compatible with CMOS and
TTL levels.
The push-pull output stages have a driver power of
typically 200 mA from 24 V and are short-circuit-proof
and current-limited, shutting down with excessive temperature.
For bus applications the output stages can
be switched to high impedance using input ENA.
To reduce the dynamic power dissipation in applications
with long lines the iC-HX uses the iC-xSwitch.
iC-HX monitors supply voltages VB and VCC and the
chip temperature, switching all output stages to high
impedance in the event of error and set NER active
low.
In addition, the device also monitors voltage differences
at the pins VB1, VB2 and VB3 and generates
an error signal if the absolute value exceeds 0.75 V.
The open-drain output NER allows the device to be
wired-ORed to the relevant NER error outputs of other
iC-HXs and iC-DLs. Via input TNER the message outputs
of other ICs can be extended to generate system
error messages. NER switches to high impedance if
supply voltage VCC ceases to be applied.
The device is protected against ESD.
