• Manufacturer Part Number: MAX3208E
• Description: (MAX3205E - MAX3208E) Dual / Quad and Hex High-Speed Differential ESD-Protection ICs
• Manufacturer: Maxim Integrated Products

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 Inter-Chassis
Interconnect. Each channel consists of a pair of diodes
that steer ESD current pulses to V
MAX3205E, MAX3207E, and MAX3208E are two, four,
and six channels (see the Functional Diagram).
The MAX3205E/MAX3207E/MAX3208E are designed to
work in conjunction with a device’s intrinsic ESD pro-
tection. The MAX3205E/MAX3207E/MAX3208E limit the
Dual, Quad, and Hex High-Speed
Differential ESD-Protection ICs

excursion of the ESD event to below ±25V peak voltage
when subjected to the Human Body Model waveform.
When subjected to the IEC 61000-4-2 waveform, the
peak voltage is limited to ±60V when subjected to
Contact Discharge. The peak voltage is limited to
±100V when subjected to Air-Gap Discharge. The
device protected by the MAX3205E/MAX3207E/
MAX3208E must be able to withstand these peak volt-
ages, plus any additional voltage generated by the par-
asitic of the board.
A TVS is integrated into the MAX3205E/MAX3207E/
MAX3208E to help clamp ESD to a known voltage. This
helps reduce the effects of parasitic inductance on the
V
ESD event. For the lowest possible clamp voltage dur-
ing an ESD event, placing a 0.1µF capacitor as close to
