MAX3221ESLLS686B –OCTOBER 2005–REVISED SEPTEMBER 2016
MAX3221E 3-Vto 5.5-V Single-Channel RS-232 Line Driver/Receiver
With ±15-kV IEC ESD Protection Features ESD Protection for RS-232 Pins ±15-kV Human-Body Model (HBM) ±8 kV (IEC 61000-4-2, Contact Discharge) ±15 kV (IEC 61000-4-2, Air-Gap Discharge) Meetsor Exceeds the Requirementsof TIA/EIA-
232-F and ITU v.28 Standards Operates With 3-Vto 5.5-V VCC Supply Operatesupto 250 kbit/s One Driver and One Receiver Low Standby Current:1 µA Typical Accepts 5-V Logic Input With 3.3-V Supply Auto-Power-Down Feature Automatically Disables
Drivers for Power Savings Alternative High-Speed Device(1 Mbit/s) SN75C3221E and SN65C3221E
Applications Battery-Powered, Hand-Held, and Portable
Equipment Notebooks and Laptops Mobile Phones and Wireless Devices
DescriptionThe MAX3221Eisa single driver, single receiver RS-
232 solution operating froma single VCC supply. The
RS-232 pins provide IEC 61000-4-2 ESD protection.
The device meets the requirementsof TIA/EIA-232-F
Flexible control options for power management are
available. Auto-power down disables driver and
charge pump when the receiveris disconnectedor
the remote driveris power down. The drivers can be
manually enabledor disabled. INVALID output goes
low when receiver inputis unconnectedor power off.
Device Information(1)(1) Forall available packages, see the orderable addendumat
the endofthe data sheet.
