General Description

The MAX3205E/MAX3207E/MAX3208E low-capaci-

tance, ±15kV ESD-protection diode arrays with an inte-

grated transient voltage suppressor (TVS) clamp are

suitable for high-speed and general-signal ESD protec-

tion. 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 puls-

es to V

or 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 V

during 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 dif-

ferential signals.

The MAX3207E is a two-channel device suitable for

USB 1.1, USB 2.0 (480Mbps), and USB OTG applica-

tions. 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 MAX3207E is available in a small 6-pin

SOT23 package. The MAX3208E is available in 10-pin

µMAX

and 16-pin, 3mm x 3mm TQFN packages. All

devices are specified for the -40°C to +125°C automo-

tive operating temperature range.

Dual, Quad, and Hex High-Speed Differential ESD-Protection ICs Design Considerations Maximum protection against ESD damage results from proper board layout (see the Layout Recommendations section). A good layout reduces the parasitic series inductance on the ground line, supply line, and protected signal lines. The MAX3205E/MAX3207E/MAX3208E ESD diodes clamp the voltage on the protected lines during an ESD event and shunt the current to GND or VCC.

MAX3205E/MAX3207E/MAX3208E Dual, Quad, and Hex High-Speed Differential ESD-Protection ICs ±15kV ESD Protection ESD protection can be tested in various ways. The MAX3205E/MAX3207E/MAX3208E are characterized for protection to the following limits: • ±15kV using the Human Body Model • ±8kV using the Contact Discharge Method specified in IEC 61000-4-2 • ±15kV using the IEC 61000-4-2 Air-Gap Discharge Method ESD Test Conditions ESD performance depends on a number of conditions.

Dual, Quad, and Hex High-Speed Differential ESD-Protection ICs 2) Use separate planes for power and ground to reduce parasitic inductance and to reduce the impedance to the power rails for shunted ESD current. 3) Ensure short low-inductance ESD transient return paths to GND and VCC. 4) Minimize conductive power and ground loops. 6) Bypass VCC to GND with a low-ESR ceramic capacitor as close to VCC as possible.
