MAX3221EEAE+

MAX3221EEAE+ is a ±15kV ESD-protected, 1µA, 3.0V to 5.5V, 250kbps, RS-232 transceiver with auto shutdown. It is a 3V-powered EIA/TIA-232 and V.28/V.24 communications interface with automatic shutdown/wakeup features, high data rate capabilities, and enhanced electrostatic discharge (ESD) protection. All transmitter outputs and receiver inputs are protected to ±15kV using IEC 1000-4-2 air gap discharge, to ±8kV using IEC 1000-4-2 contact discharge, and to ±15kV using the human body model. This device achieves a 1µA supply current with the revolutionary Auto Shutdown™ feature. It saves power without changes to the existing BIOS or operating system by entering low-power shutdown mode when the RS-232 cable is disconnected, or when the transmitters of the connected peripherals are off. It is used in applications such as notebooks, subnotebooks, and palmtop computers, cellular phones, battery-powered equipment, handheld equipment, peripherals, and printers.

• Supply current, auto shutdown is 1µA typical at (VCC = +3.0V to +5.5V, C1–C4 = 0.1µF)
• Transmitter input hysteresis is 0.5V typical at (VCC = +3.0V to +5.5V, C1–C4 = 0.1µF)
• Input leakage current is ±0.01µA typical at (VCC = +3.0V to +5.5V, C1–C4 = 0.1µF)
• Maximum data rate is 250kbps minimum at (RL = 3Kohm, CL = 1000pF, one transmitter switching)
• Transition-region slew rate is 30V/µs maximum at (CL = 150pF to 1000pF)
• Receiver propagation delay is 0.15µs typical at (CL = 150pF, TA = +25°C)
• Input resistance is 5Kohm typical at (VCC = +3V to +5.5V, C1–C4 = 0.1µF)
• Operating temperature range from -40°C to +85°C
• 16-lead SSOP package
