Package

The MAX3227E consists of one line driver, one line receiver, and a dual charge-pump circuit with ± 15-kV IEC

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/ μ 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 MAX3227E achieves a 1- μ 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 MAX3227EC is characterized for operation from 0 ° C to 70 ° C. The MAX3227EI is characterized for

operation from –40 ° C to 85 ° C.
