GENERAL DESCRIPTION
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.
A shutdown input disables the charge pump and puts the device
into a low power shutdown mode, in which the current
consumption is typically less than 1 μA. The transmitter is
disabled during shutdown but the receiver remains functional.
An epitaxial BiCMOS construction minimizes power consumption
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 available in a 10-lead MSOP package, which
makes it ideal for serial communications in small, portable
applications such as palmtop computers and mobile telephones,
where a full, RS-232 serial interface is not required, but compact
size and low power drain are paramount.
