The ADM202E and ADM1181A are robust, high speed, 2-channel RS232/V.28 interfaces that incorporate CMOS inputs, outputs, voltage doublers, and voltage inverters. They feature EMI/EMC compliance and 15 kV ESD protection and operate over a voltage range of 5 V to 10 V.
The ADM202E and ADM1181A are high‑speed, two‑channel RS‑232/V.28 interface devices that operate from a single +5 V supply. They meet EU EMC directives, provide low EMI emissions, and include extensive ESD (up to +15 kV) and EFT protection, making them suitable for harsh electrical environments and portable instruments.
Technical specifications include an operating voltage range of 4.5‑5.5 V, typical supply current of 2‑3 mA, maximum data rate of 230 kbps, and various package options (DIP, narrow/wide SO, TSSOP). The devices also feature internal pull‑down resistors, charge‑pump voltage conversion, and compliance with EIA‑232R and CCITT V.28 standards.
