This document introduces the features and characteristics of the ADM3307E/ADM3310E/ADM3311E/ADM3312E/ADM3315E series of products. This series of products are 2.7 V to 3.6 V power supply serial port transceivers with Green Idle low power mode, single power supply, 3 V logic, 0.1 μF to 1 μF charge pump capacitors, low EMI, low power shutdown: 20 nA, full RS-232 compliance, 460 kb/s data rate, one receiver active in shutdown (ADM3307E/ADM3311E/ADM3312E/ADM3315E), two receivers active in shutdown (ADM3310E), ESD>15 kV IEC 1000-4-2 on RS-232 I/Os, ESD>15 kV IEC 1000-4-2 on CMOS and RS-232 I/Os (ADM3307E).
The ADM33xxE family of driver/receiver devices meets the EIA‑232 standard while operating from a single 2.7 V to 3.6 V supply. They include an on‑board charge‑pump DC‑DC converter, Green Idle power‑saving mode, and extensive ESD protection up to 15 kV. The devices are intended for portable and battery‑powered equipment such as mobile phones, laptops, PDAs, and data‑cable applications.
The datasheet provides functional block diagrams, pin‑out tables, electrical specifications, absolute maximum ratings, and a product selection guide. It also lists the various package options (LFCSP‑VQ, TSSOP, SSOP) and outlines the shutdown feature that reduces power consumption to the nanowatt range while keeping one or two receivers active for monitoring peripheral activity.
| Operating Voltage Range | 2.7 V to 3.6 V |
|---|---|
| Shutdown Supply Current | 0.02 µA |
| ESD Protection (RS‑232 I/Os) | >15 kV IEC 1000‑4‑2 |
| Charge Pump Output Voltage (V+) | +7.25 V (no load) |
The shutdown supply current is specified as 0.02 µA.
Two receivers remain active in shutdown mode for the ADM3310E.
The RS‑232 pins are protected against electrostatic discharge up to more than 15 kV per IEC 1000‑4‑2.
