The ADM101E is a single channel RS-232 driver and receiver inthe Analog Devices Craft Port series, designed to operate from asingle, 5 V supply. A highly efficient charge-pump voltage invertergenerates an on-chip –5 V supply, which eliminates the needfor a negative power supply for the driver and permits RS-232compatible output levels to be developed using charge pumpcapacitors as small as 0.1 μF.A shutdown input disables the charge pump and puts the deviceinto a low power shutdown mode, in which the current consumptionis typically less than 1 μA. The transmitter is disabledduring shutdown but the receiver remains functional. Craft Port is a trademark of Analog Devices, Inc.An epitaxial BiCMOS construction minimizes power consumptionto 3 mW and also guards against latch-up. Overvoltageprotection is provided allowing the receiver inputs to withstandcontinuous voltages in excess of ±30 V. In addition, all I-O pinshave ESD protection to levels greater than 15 kV.The ADM101E is available in a 10-lead μSOIC package, whichmakes it ideal for serial communications in small, portableapplications such as palmtop computers and mobile telephones,where a full, RS-232 serial interface is not required, but compactsize and low power drain are paramount.
