GENERAL DESCRIPTION

An epitaxial BiCMOS construction minimizes power consump-

tion to 3 mW and also guards against latch-up. Overvoltage

protection is provided allowing the receiver inputs to withstand

continuous voltages in excess of ±30 V. In addition, all I-O pins

have ESD protection to levels greater than 15 kV.

The ADM101E is a single channel RS-232 driver and receiver in

the Analog Devices Craft Port series, designed to operate from a

single, +5 V supply. A highly efficient charge-pump voltage

inverter generates an on-chip –5 V supply, which eliminates the

need for a negative power supply for the driver and permits

RS-232 compatible output levels to be developed using charge

pump capacitors as small as 0.1 µF.

The ADM101E is available in a 10-lead µSOIC package, which

makes it ideal for serial communications in small, portable ap-

plications such as palmtop computers and mobile telephones,

where a full, RS-232 serial interface is not required, but com-

pact size and low power drain are paramount.

A shutdown input disables the charge pump and puts the device

into a low power shutdown mode, in which the current con-

sumption is typically less than 1 µA. The transmitter is disabled

during shutdown but the receiver remains functional.
