GENERAL DESCRIPTION The ADM202 is a 2-channel RS-232 line driver/receiver pair designed to operate from a single 5 V power supply. A highly efficient on-chip charge pump design permits RS-232 levels to be developed using charge pump capacitors as small as 0.1 µF. This converter generates ±10 V RS-232 output levels. An epitaxial BiCMOS construction minimizes power consumption to 10 mW and guards against latch-up. Overvoltage protection is provided, allowing the receiver inputs to withstand continuous voltages in excess of ±30 V. In addition, all pins contain ESD protection to levels greater than 2 kV. The ADM202 meets or exceeds the TIA/EIA-232-E and V.28 specifications. Fast driver slew rates permit 120 kB operation, and high drive currents allow extended cable lengths. The ADM202 is available in a 16-lead PDIP and both narrow and wide 16-lead SOIC packages. Rev. B Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
