ADI AD239JN

The AD230 family of 5V only, RS - 232 line drivers/receivers provides a variety of configurations to fit most communication needs, especially in applications where ±12V is not available. The AD230, AD235, AD236 and AD241 feature a low power shutdown mode which reduces power dissipation to less than 5 μW making them ideally suited for battery powered equipment. The AD233 and AD235 do not require any external components and are particularly useful in applications where printed circuit board space is critical. The AD230 - AD241 family of RS - 232 drivers/receivers are designed to solve interface problems by meeting the RS - 232 - C specifications while using a single digital +5V supply. The RS232 - C standard requires transmitters which will deliver ±5V minimum on the transmission channel and receivers which can accept signal levels down to ±3V. The AD230 - AD241 meet these requirements by integrating step up voltage converters and level - shifting transmitters and receivers onto the same chip. CMOS technology is used to keep the power dissipation to an absolute minimum. A comprehensive range of transmitter/receiver combinations is available to cover most communications needs. The AD230, AD235, AD236 and AD241 are particularly useful in battery powered systems as they feature a low power shutdown mode which reduces power dissipation to less than 5 μW. The AD233 and AD235 are designed for applications where space saving is important as the charge pump capacitors are molded into the package.
