ADM202JRN

高速，+ 5 V， 0.1 uF的CMOS RS - 232驱动器/接收器 High Speed, +5 V, 0.1 uF CMOS RS-232 Driver/Receivers

Product Details

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.

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.

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 is available in a 16-lead PDIP and both narrow and wide 16-lead SOIC packages.
