ADM5170:  OCTAL LINE DRIVER SUITABLE FOR DIGITAL COMMUNICATION SYSTEMS WITH DATA RATES UP TO 116 KB/S

The ADM5170 is an octal line driver suitable for digital communication systems with data rates up to 116 kB/s. Input TTL 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 VDD and MS- ...More

ADM5170:  OCTAL LINE DRIVER SUITABLE FOR DIGITAL COMMUNICATION SYSTEMS WITH DATA RATES UP TO 116 KB/S

Product Description

The ADM5170 is an octal line driver suitable for digital communication systems with data rates up to 116 kB/s. Input TTL 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 VDD and MS- connected to VSS, RS-232 operation is selected.

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 kOhm and 10 kOhm may be selected giving a slew rate which can be adjusted from 10 V/µs to 2.2 V/µs. This adjustment of the slew rate allows tailoring of the output characteristics 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.
