The ADM3307E/ADM3310E/ADM3311E/ADM3312E/ADM3315E are 2.7V to 3.6V serial port transceivers with Green Idle™ power-saving mode, reducing power consumption. This series of devices adopt single power supply, operate with 3V logic, have low EMI, low power shutdown (20 nA), full RS-232 compliance and 460kb/s data rate. In addition, they also have ESD >15 kV IEC 1000-4-2 on RS-232 I/O and ESD >15 kV IEC 1000-4-2 on CMOS and RS-232 I/O. These products are suitable for mobile phone handsets/data cables, laptop and notebook computers, printers, peripherals, modems, PDAs/Hand-Held Devices/Palmtop Computers, etc.
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 a shutdown facility that reduces consumption to tens of nanoamps. ESD protection of up to 15 kV (IEC 1000‑4‑2) is provided on all I/O pins, making the parts suitable for harsh electrical environments and portable applications such as mobile phones, laptops, PDAs and data cables.
The series is offered in 32‑lead LFCSP_VQ (5 mm × 5 mm) and various TSSOP packages (28‑lead for ADM3307E/ADM3310E/ADM3311E, 24‑lead for ADM3312E/ADM3315E). The datasheet lists detailed pin configurations, functional block diagrams, absolute maximum ratings, and a product selection guide to help designers choose the appropriate device for their data‑rate and power‑budget requirements.
