The MAX3205E/MAX3207E/MAX3208E low-capacitance, ±15kV ESD-protection diode arrays with an integrated transient voltage suppressor (TVS) clamp are suitable for high-speed and general-signal ESD protection. Low input capacitance makes these devices ideal for ESD protection of signals in HDTV, PC monitors (DVI™, HDMI®), PC peripherals (FireWire®, USB 2.0), server interconnect (PCI Express®, InfiniBand™), datacom, and interchassis interconnect. Each channel consists of a pair of diodes that steer ESD current pulses to VCCor GND.The MAX3205E/MAX3207E/MAX3208E protect against ESD pulses up to ±15kV Human Body Model, ±8kV Contact Discharge, and ±15kV Air-Gap Discharge, as specified in IEC 61000-4-2. An integrated TVS ensures that the voltage rise seen on VCCduring an ESD event is clamped to a known voltage. These devices have a 2pF input capacitance per channel, and a channel-to-channel capacitance variation of only 0.05pF, making them ideal for use on high-speed, single-ended, or differential signals.The MAX3207E is a two-channel device suitable for USB 1.1, USB 2.0 (480Mbps), and USB OTG applications. The MAX3208E is a four-channel device for Ethernet and FireWire applications. The MAX3205E is a six-channel device for cell phone connectors and SVGA video connections.The MAX3205E is available in 9-bump, tiny wafer-level package (WLP) and 16-pin, 3mm x 3mm, thin QFN packages.

The MAX3209E is a complete, dual DTE RS-232 serial port (6 transmitters, 10 receivers) for motherboards and desktop PCs that ensures compliance with the stringent ESD requirements of the European Community. The device minimizes board space and power consumption by eliminating the need for a negative power supply; it integrates two serial ports and a charge pump into a single 38-pin TSSOP package.The MAX3209E features a 50µA low-power standby mode for compliance with system power-management requirements. During standby, while the device operates from the single +3V to +5.5V logic supply, one receiver on each port remains active, allowing automatic system wake-up when peripheral communications resume.All transmitter outputs and receiver inputs are protected to ±15kV using IEC 1000-4-2 Air-Gap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge, and ±15kV using the Human Body Model, making the device ideal for use in harsh environments or mission-critical equipment. In addition, the MAX3209E withstands ±4kV per IEC 1000-4-4 Electrical Fast Transient/Burst Stressing. As a result of its robust charge-pump structure, the MAX3209E guarantees mouse driveability and true RS-232 operation at data rates up to 460kbps, ensuring compatibility with PC-to-PC communication software (such as LapLink®).ApplicationsComputers: Desktop, Workstation, ServerEquipment Requiring IEC 1000-4-2 ComplianceInstrumentsMotherboardsNetwork ServersTelecommunications

The MAX3212 uses Maxim's new proprietary AutoShutdown mode to reduce supply current to 1µA. The MAX3212, with 3 RS-232 drivers and 5 RS-232 receivers, is intended for 2.7V to 3.6V-powered EIA/TIA-232E and V.28/V.24 serial interface. True RS-232 levels are maintained across the operating range. A guaranteed data rate of 235kbps provides compatibility with popular software for communicating with personal computers.Supply current is reduced to 1µA with Maxim's new AutoShutdown feature. When the MAX3212 does not sense a valid signal level on the receiver inputs, the on-board power supply and drivers shut down. This occurs if the RS-232 cable is disconnected or if the transmitters of the connected peripheral are turned off. The system turns on again when a valid level is applied to any RS-232 receiver input. As a result, the system saves power without changes to the existing software.A second power-management feature is incorporated to permit automatic shutdown when the RS-232 connection is valid but inactive. In this case, a transition detector facilitates shutdown when the receivers are presented with stationary RS-232 levels for long periods.Three-state drivers are provided on receiver outputs so that multiple receivers, generally of different interface standards, can be wire-ORed at the UART. The MAX3212 is available in 28-pin SO and SSOP packages.ApplicationsBattery-Powered ApplicationsInstrumentsNotebook and Palmtop ComputersPeripherals

The MAX320/MAX321/MAX322 are precision, dual, SPST analog switches designed to operate from ±3V to ±8V dual supplies. The MAX320 has two normally open (NO) switches and the MAX321 has two normally closed (NC) switches. The MAX322 has one NO and one NC switch. Low power consumption (1.25mW) makes these parts ideal for battery-powered equipment. They offer low leakage currents (100pA max) and fast switching speeds (tON= 150ns max, tOFF= 100ns max).The MAX320 series, powered from ±5V supplies, offers 35Ω max on-resistance (RON), 2Ω max matching between channels, and 4Ω max RONflatness.These switches also offer 5pC max charge injection and a minimum of 2000V ESD protection per Method 3015.7. For equivalent devices specified for single-supply operation, see the MAX323/MAX324/MAX325 data sheet.

The MAX3221/MAX3223/MAX3243 achieve 1µA supply current with Maxim’s revolutionary AutoShutdown™feature. When the MAX3221/MAX3223/MAX3243 do not sense a valid signal level on their receiver inputs, the on-board power supply and drivers shut down. This occurs if the RS-232 cable is disconnected or if the transmitters of the connected peripheral are turned off. The system turns on again when a valid level is applied to any RS-232 receiver input.The MAX3221/MAX3223/MAX3243 require only 0.1µF capacitors in 3.3V operation, and can operate from input voltages ranging from +3.0V to +5.5V.A proprietary, high-efficiency, dual charge-pump power supply and a low-dropout transmitter combine to deliver true RS-232 performance from a single +3.0V to +5.5V supply.The MAX3221 is a 1-driver/1-receiver 16-pin SSOP version of the 20-pin 2-driver/2-receiver MAX3223.The MAX3243 is a 3-driver/5-receiver with a complementary always-active receiver for external monitoring in a variety of 28 pin packages.
