Low Power, +5V CMOS RS-232 Transceiver With 2 Drivers And 2 ReceiversThe ADM2xx family of Line Drivers receivers is intended for all
EIA-232-E and V.28 Communications Interfaces especially in
applications where 12 V is not available. The ADM223,
ADM230L, ADM235L, ADM236L and ADM241L feature a low power shutdown mode that reduces power dissipation to less than 5 W, making them ideally suited for battery powered equipment. Two receivers remain enabled during shutdown on
the ADM223. The ADM233L and ADM235L do not require
any external components and are particularly useful in applications
where printed circuit board space is critical.
All members of the ADM230L family, except the ADM231L
and the ADM239L include two internal Charge Pump voltage
converters that allow operation from a single +5 V supply.
These converters convert the +5 V input power to the 10 V
required for RS-232 output levels. The ADM231L and
ADM239L are designed to operate from +5 V and +12 V supplies.
An internal +12 V to -12 V Charge Pump voltage converter
generates the -12 V supply.
The ADM2xxL is an enhanced upgrade for the AD2xx family featuring lower power consumption, faster slew rate and operation with smaller (1 F) capacitors. By Analog Devices, Inc. |
