Auto-Powerdown Feature Automatically

Disables Drivers for Power Savings

DESCRIPTION/ORDERING INFORMATION

The MAX3221E is a single driver, single receiver RS-232 solution operating from a single V_CCsupply. The

RS-232 pins provide IEC G1000-4-2 ESD Protection. 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. These devices operate at data signaling rates up to 250 kbit/s and a maximum of 30-V/µs driver output

slew rate.

Flexible control options for power management are available when the serial port is inactive. The

auto-powerdown feature functions when FORCEON is low and FORCEOFF is high. During this mode of

operation, if the device does not sense a valid RS-232 signal on the receiver input, the driver output is disabled.

If FORCEOFF is set low and EN is high, both the driver and receiver are shut off, and the supply current is

reduced to 1 µA. Disconnecting the serial port or turning off the peripheral drivers causes the auto-powerdown

condition to occur. Auto-powerdown can be disabled when FORCEON and FORCEOFF are high. With

auto-powerdown enabled, the device is activated automatically when a valid signal is applied to the receiver

input. The INVALID output notifies the user if an RS-232 signal is present at the receiver input. INVALID is high

(valid data) if the receiver input voltage is greater than 2.7 V or less than –2.7 V, or has been between –0.3 V

and 0.3 V for less than 30 µs. INVALID is low (invalid data) if the receiver input voltage is between –0.3 V and

0.3 V for more than 30 µs. Refer to Figure 5 for receiver input levels.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
