Dual Driver/Comparator/Load
with Internal DACs
General Description
The MAX9973/MAX9974 fully integrated, high-perfor-
mance, dual-channel pin electronics driver/compara-
tor/load (DCL) with built-in level-setting digital-to-analog
converters (DACs) are ideally suited for memory and
SOC automatic test equipment (ATE) applications.
Each channel includes a three-level pin driver, a win-
dow comparator, dynamic clamps, a 1kΩ load, and
seven independent level-setting DACs.
The driver features a wide voltage range and high-speed
operation, includes high-impedance and active-termina-
tion (3rd-level drive) modes, and is highly linear even at
low voltage swings. Additionally, the driver provides high-
speed differential multiplexer control inputs, with internal
termination resistors that are compatible with ECL, LV-
PECL, LVDS, and GTL. The window comparators provide
extremely low timing variation over changes in slew rate,
pulse width, or overdrive voltage, and have open-collec-
tor outputs. When high-impedance mode is selected, the
dynamic clamps provide damping of high-speed device-
under-test (DUT) waveforms. The load facilitates fast con-
tact testing when used in conjunction with the
comparators, and functions as a pullup for
open-drain/collector DUT_ outputs. The MAX9973/
MAX9974 are configured through a serial interface.
The MAX9973/MAX9974 differ in two aspects: the posi-
tion of the exposed heat slug and the pin arrangement.
The MAX9973G/MAX9974G comparator outputs sink
8mA (typ), while the MAX9973H/MAX9974H compara-
tor outputs sink 16mA (typ). The devices are available
in a 64-pin (10mm x 10mm x 1.00mm) TQFP-EP pack-
age with an exposed paddle on top (MAX9973) or bot-
tom (MAX9974) for heat removal. Power dissipation is
only 700mW per channel. The full operating voltage
range is -1.5V to +6.5V. Operation is specified at an
internal die temperature of +40°C to +100°C, and fea-
tures a temperature monitor output.
