FEATURES
120 kB transmission rate Small (0.1 µF) charge pump capacitors Single 5 V power supply Meets TIA/EIA-232-E and V.28 specifications 2 drivers and 2 receivers On-board dc-to-dc converters ±9 V output swing with 5 V supply Low power BiCMOS: 2.5 mA ICC ±30 V receiver input levels APPLICATIONS
Computers Peripherals Modems Printers Instruments GENERAL DESCRIPTION
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. Fast driver slew rates permit 120 kB operation, and high drive currents allow extended cable lengths. High Speed, 5 V, 0.1 µF CMOS RS-232 Driver/Receiver ADM202 TYPICAL APPLICATION CIRCUIT 5V INPUT 0.1µF + 6.3V 1 C1+ 3 C1– +5V TO +10V VOL
