Standard RS232B). The addition of the diodes
also permits the MC1488 to withstand faults with
power-supplies of less than the 9.0 V stated
above.
The maximum short-circuit current allowable
under fault conditions is more than guaranteedby
the previously mentioned 10 mA output current
limiting.
The MC1488 is an extremely versatile line driver
with a miriad of possible applications. Several
features of the drivers enhancethis versatility:
1. Output Current Limiting - this enables the
circuit designer to define the ouptut voltagelevels
independent of power-supplies and can be
accomplished by diode clamping of the output
pins.
2. Power-Supply Range - as can be seen from
the schematic drawing of the drivers, the positive
and negative driving elements of the device are
essentially independent and do not
matching power-supplies. In fact, the positive
supply can very from a minimum seven volts
(required for
driving
the
section) to the maximum specified 15 V. The
negative supply can vary from approximately -
2.5 V to the minimum specified - 15 V. The
MC1488 will drive the ouptut to within 2 V of the
positive or negative supplies as long as the
current output limits are not exceeded. The
combination
of
the
supply-voltage features allow a wide combination
of possible outputs within
package.
