Analog Devices provides information on the ADM222/ADM232A/ADM242 high-speed RS-232 drivers/receivers, offering transmission rates up to 200 kB/s.
The devices operate from a single 5 V power supply and use a charge pump with small external capacitors to develop RS-232 bipolar levels.
The devices are fabricated on BiCMOS technology, allowing for high transmission rates while minimizing power supply current.
The ADM232A is a pin-compatible, high-speed upgrade for the AD232 and ADM232L.
The ADM222 includes a shutdown function to minimize power consumption, while the ADM242 combines shutdown and enable functions.
The devices are suitable for use in computers, peripherals, modems, printers, and instruments.
The specifications and test circuits for the devices are also provided.
Analog Devices does not assume responsibility for the use of the information provided or any infringements of patents or other rights of third parties resulting from its use.
No license is granted by implication or otherwise under any patent or patent rights of Analog Devices.
