This datasheet introduces the features and characteristics of the Analog Devices ADM101E RS-232 transceiver.
The ADM101E is a compact, single‑channel RS‑232 driver and receiver in the Analog Devices Craft Port series. It operates from a single 5 V supply and includes an on‑chip charge‑pump DC‑DC converter that generates the required –5 V rail, eliminating the need for an external negative supply. The device offers a 460 kbit/s transmission rate, ultralow power shutdown mode (typical <1 µA), and ESD protection on all I/O pins.
The datasheet provides detailed electrical specifications, pin functions, circuit description, and mechanical dimensions for the 10‑lead SOIC package. Typical applications include mobile phones, palmtop computers, PDAs, GPS receivers, and other portable instrumentation where a full RS‑232 interface is unnecessary.
