GENERAL DESCRIPTION
The ADM5170 is an octal line driver suitable for digital communi-
cation systems with data rates up to 116 kB/s. Input TTL or
CMOS signal levels are inverted and translated into either EIA
Mode Select inputs MS+ and MS–. With both Mode Select inputs
at GND, RS-423 operation is selected while with MS+ connected
to V
The output slew rates may be controlled using an external resistor
connected between the SRA (Slew Rate Adjust) pin and GND.
Resistor values between 2 k and 10 k may be selected giving a
slew rate which can be adjusted from 10 V/ s to 2.2 V/ s. This
adjustment of the slew rate allows tailoring of the output character-
istics to suit the interface cable being used.
The outputs may be disabled using the EN (Enable Input). This
feature permits sharing of a common output line.
The ADM5170 is fabricated on an advanced CMOS process
featuring low power consumption. In the disabled state the power
consumption reduces from 500 mW to 40 mW. The ADM5170 is
available in both 28-pin DIP and 28-lead PLCC packages.
