The DS229 is a triple RS-232 driver/receiver pair that generates RS-232 voltage levels from a single +5-volt power supply. It is fully compliant with EIA RS-232E and V.28/V.24 standards. The DS229 contains three drivers and three receivers.
The DS229 provides three RS‑232 drivers and three receivers in a single IC, generating the required ±10 V levels from a single +5 V supply using on‑board charge‑pump converters. It complies with EIA‑232E and V.28 standards, supports data rates up to 116 kbits/s, and requires only 0.1 µF charge‑pump capacitors.
The device is offered in 20‑pin DIP, SOIC, and TSSOP packages and includes detailed electrical characteristics such as operating voltage, current consumption, output swing, and timing parameters. Absolute maximum ratings and recommended operating conditions are also provided for reliable design.
