Description

The ADM202 is a 2-channel RS-232 line driver/receiver pairdesigned to operate from a single 5 V power supply. A highlyefficient on-chip charge pump design permits RS-232 levels tobe developed using charge pump capacitors as small as 0.1 µF.This converter generates ±10 V RS-232 output levels.The ADM202 meets or exceeds the TIA/EIA-232-E and V.28specifications. Fast driver slew rates permit 120 kB operation,and high drive currents allow extended cable lengths.An epitaxial BiCMOS construction minimizes power consumptionto 10 mW and guards against latch-up. Overvoltageprotection is provided, allowing the receiver inputs to withstandcontinuous voltages in excess of ±30 V. In addition, all pinscontain ESD protection to levels greater than 2 kV.The ADM202 is available in a 16-lead PDIP and both narrowand wide 16-lead SOIC packages.Applications Computers Peripherals Modems Printers Instruments
