Status

All versions are No Longer Available. See Ordering Information for recommended replacements.

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.
