The device meets the requirements ofTIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller andthe serial-port connector. The charge pump and four small external capacitors allow operation from a single 3-Vto 5.5-V supply. These devices operate at data signaling rates up to 250 kbit/s and a maximum of 30-V/µs driveroutput slew NG INFORMATIONTASSOP (DB)−0°C to 70°CTSSOP (PW)SSOP (DB)−40°C to 85°CTSSOP (PW)PACKAGE†Tube of 80Reel of 2000Tube of 90Reel of 2000Tube of 80Reel of 2000Tube of 90Reel of 2000ORDERABLEPART NUMBERMAX3221CDBMAX3221CDBRMAX3221CPWMAX3221CPWRMAX3221IDBMAX3221IDBRMAX3221IPWMAX3221IPWRTOP-SIDEMARKINGMA3221CMA3221CMB3221IMB3221I†Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines areavailable at /sc/ be aware that an important notice concerning availability, standard warranty, and use in critical applications ofTexasInstruments semiconductor products and disclaimers thereto appears at the end of this data TION DATA information is current as of publication ts conform to specifications per the terms of Texas Instrumentsstandard warranty.

Theauto-powerdown feature functions when FORCEON is low and FORCEOFF is high. During this mode ofoperation, if the device does not sense a valid RS-232 signal on the receiver input, the driver output is FORCEOFF is set low and EN is high, both the driver and receiver are shut off, and the supply current isreduced to 1 µA. Disconnecting the serial port or turning off the peripheral drivers causes the auto-powerdowncondition to occur. Auto-powerdown can be disabled when FORCEON and FORCEOFF are high. Withauto-powerdown enabled, the device is activated automatically when a valid signal is applied to the receiverinput. 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 Vand 0.3 V for less than 30 µs. INVALID is low (invalid data) if the receiver input voltage is between −0.3 V and0.3 V for more than 30 µs.

The device meets the requirements ofTIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller andthe serial-port connector. The charge pump and four small external capacitors allow operation from a single 3-Vto 5.5-V supply.

Theauto-powerdown feature functions when FORCEON is low and FORCEOFF is high. During this mode ofoperation, if the device does not sense a valid RS-232 signal on the receiver input, the driver output is FORCEOFF is set low and EN is high, both the driver and receiver are shut off, and the supply current isreduced to 1 µA. Disconnecting the serial port or turning off the peripheral drivers causes the auto-powerdowncondition to occur. Auto-powerdown can be disabled when FORCEON and FORCEOFF are high. Withauto-powerdown enabled, the device is activated automatically when a valid signal is applied to the receiverinput. 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 Vand 0.3 V for less than 30 µs. INVALID is low (invalid data) if the receiver input voltage is between −0.3 V and0.3 V for more than 30 µs.
