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. Craft Port is a trademark of Analog Devices, Inc. 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 μSOIC 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.
