The ADM101EARMZ is a 1-channel Craft Port? Tiny RS-232 Transceiver for portable applications designed to operate from a single 5V supply. A highly efficient charge-pump voltage inverter generates an on-chip -5V 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 0.1μF. 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 1μA. The transmitter is disabled during shutdown but the receiver remains functional. An epitaxial BiCMOS construction minimizes power consumption to 3mW and also guards against latch-up. Overvoltage protection is provided allowing the receiver inputs to withstand continuous voltages in excess of ±30V. In addition, all I-O pins have ESD protection to levels greater than 15kV.
