The document provides information about the features and characteristics of products from the company Dinghao, including inventory, technical data, encyclopedia information, and hot topics.
The ADM2xxE family comprises robust RS‑232 and V.28 interface devices that operate from a single +5 V supply and meet the EU EMC Directive 89/336/EEC. They provide high ESD protection, fast transient burst immunity, and low EMI emissions, making them suitable for harsh electrical environments such as laptops, printers, and modems.
Key features include up to 230 kbps data rate (460 kbps for the ADM206E), shutdown mode with 5 pW power consumption, and a variety of package options (DIP, SO, SSOP, TSSOP). The document provides functional block diagrams, pin‑out tables, absolute maximum ratings, and performance curves for each model.
| Operating Voltage Range | +5.0 V ±10 % |
|---|---|
| Maximum Data Rate | 230 kbps (460 kbps for ADM206E) |
| Shutdown Supply Current | 5 pA |
| ESD Protection (I‑O pins) | +15 kV Human Body Model |
| Input Logic Threshold Low | 0.8 V |
| Output Voltage Swing | +5.0 V to +9.0 V |
The devices support data rates up to 230 kbps, with the ADM206E capable of 460 kbps.
Shutdown disables the charge pump and transmitter outputs, reducing power consumption to about 5 pW; some receiver outputs remain active to detect peripheral activity.
The I‑O pins are protected up to +15 kV Human Body Model.
