Package
The MAX3227 consists of one line driver, one line receiver, and a dual charge-pump circuit with
±15-kV ESD
protection pin to pin (serial-port connection pins, including GND). The device meets the requirements of
TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the
serial-port connector. The charge pump and four small external capacitors allow operation from a single 3-V to
5.5-V supply. This device operates at data-signaling rates of 1 Mbit/s in normal operating mode and a maximum
of 30-V/
s driver output slew rate. This device also features a logic-level output (READY) that asserts when the
charge pump is regulating and the device is ready to begin transmitting.
The MAX3227 achieves a 1-
A supply current using the auto-powerdown plus feature. This device automatically
enters a low-power powerdown mode when the RS-232 cable is disconnected or the drivers of the connected
peripherals are inactive for more than 30 s. They turn on again when they sense a valid transition at any driver or
receiver input. Auto-powerdown saves power without changes to the existing BIOS or operating system.
The MAX3227C is characterized for operation from 0
°C to 70°C. The MAX3227I is characterized for operation
from –40
°C to 85°C.
