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 chargepump
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
drain is typically less than 5 μA.
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 voltage in excess of ±30 V. In addition, all pins have
ESD protection to levels
