Description

The DS232A is a dual RS-232 driver/receiver pair that generates RS-232 voltage levels from a single +5-volt power supply. Additional ±12-volt supplies are not needed since the DS232A uses on-board charge pumps to convert the +5-volt supply to ±10 volts. The DS232A is fully compliant with EIA RS-232E and V.28/V.24 standards. The DS232A contains two drivers and two receivers. Driver slew rates and data rates are guaranteed up to 250k bits/sec. The DS232A operates with only 0.1 µF charge pump capacitors.

Key Features

Compatible with LT1181A and MAX232A High data rate - 250 kbits/sec under load 16-pin DIP or SOIC package 20-pin TSSOP package for height restricted applications Operate from single +5V power Meets all EIA-232E and V.28 specifications Uses small capacitors: 0.1 µF Optional industrial temperature range available (-40°C to +85°C)
