GENERAL D ESCRIP TIO N

T he ADM5170 is an octal line driver suitable for digital communi-

cation systems with data rates up to 116 kB/s. Input T T L or

CMOS signal levels are inverted and translated into either EIA

RS-232E or RS-423A signal levels depending on the status of the

Mode Select inputs MS+ and MS–. With both Mode Select inputs

at GND, RS-423 operation is selected while with MS+ connected

to V_DDand MS– connected to V_SS, RS-232 operation is selected.

SLEW RATE

CONTROL

T he output slew rates may be controlled using an external resistor

connected between the SRA (Slew Rate Adjust) pin and GND.

Resistor values between 2 kΩ and 10 kΩ may be selected giving a

slew rate which can be adjusted from 10 V/µs to 2.2 V/µs. T his

adjustment of the slew rate allows tailoring of the output character-

istics to suit the interface cable being used.

T he outputs may be disabled using the EN (Enable Input). T his

feature permits sharing of a common output line.

RS-423A

T he 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. T he ADM5170 is

available in both 28-pin DIP and 28-lead PLCC packages.
