ADM242AR Description

Short technical summary and product information.

The ADM242AR is a BiCMOS RS-232 transceiver from Analog Devices / Maxim Integrated. It integrates two drivers and two receivers for full-duplex serial communication. The device operates from a single 4.5V to 5.5V supply and uses an on-chip charge pump with small 0.1µF capacitors to generate RS-232 voltage levels. It supports data rates up to 200 kbps and meets EIA-232-E and V.28 specifications. The receiver hysteresis is 400 mV for noise immunity.

 

The ADM242AR is housed in an 18-lead SOIC package (0.295" width, 7.50mm) and is surface mountable. It operates over the industrial temperature range of -40°C to +85°C. This transceiver is suitable for applications in computers, peripherals, modems, printers, and instruments.
