Quad Low-Power, 500Mbps
ATE Driver/Comparator
General Description
The MAX9965/MAX9966 four-channel, low-power, high-
speed pin electronics driver and comparator ICs
include for each channel a three-level pin driver, com-
parator, and variable clamps. The MAX9965/MAX9966
are similar to the MAX9963/MAX9964, but with even
lower window comparator dispersion for enhanced
accuracy. The driver features a wide voltage range and
high-speed operation, includes high-Z and active termi-
nation (3rd-level drive) modes, and is highly linear even
at low-voltage swings. The dual bipolar-input compara-
tor provides very low dispersion (timing variation) over a
wide variety of input conditions. The clamps provide
damping of high-speed DUT waveforms when the
device is configured as a high-impedance receiver.
High-speed, differential control inputs compatible with
ECL, LVPECL, LVDS, and GTL levels are provided for
each channel. ECL/LVPECL or flexible open-collector
outputs are available for the comparators.
The A-grade version provides tight matching of gain
and offset for the driver and comparator, allowing refer-
ence levels to be shared across multiple channels in
cost-sensitive systems. For system designs that incor-
porate independent reference levels for each channel,
the B-grade version is available at reduced cost.
Optional internal resistors at the high-speed inputs pro-
vide differential termination of LVDS inputs, while
optional internal resistors provide the pullup voltage
and source termination for open-collector comparator
outputs. These features significantly reduce the dis-
crete component count on the circuit board.
The MAX9965/MAX9966 operating range is -1.5V to
+6.5V, with powerdissipation of only 975mW per channel.
These devices are available in a 100-pin, 14mm x
14mm body, 0.5mm pitch TQFP with an exposed 8mm
x 8mm die pad on the top (MAX9965) or bottom
(MAX9966) of the package for efficient heat removal.
The MAX9965/MAX9966 are specified to operate with
an internal die temperature of +60°C to +100°C, and
feature a die temperature monitor output.

*Dissipation
wattage values are based on still air with no heat sink for the MAX9965 and slug soldered to board copper for the MAX9966.
Actual maximum power dissipation is a function of users’ heat extraction technique and may be substantially higher.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
