.. 19-0690; Rev 0; 1/07 Dual Driver/parator/Load with Internal DACs General Description The MAX9973/MAX9974 fully integrated, high-performance, dual-channel pin electronics driver/parator/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 window parator, 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-termination (3rd-level drive) modes, and is highly linear even at low voltage swings. Additionally, the driver provides highspeed differential multiplexer control inputs, with internal termination resistors that are patible with ECL, LVPECL, LVDS, and GTL. The window parators provide extremely low timing variation over changes in slew rate, pulse width, or overdrive voltage, and have open-collector outputs. When high-impedance mode is selected, the dynamic clamps provide damping of high-speed deviceunder-test (DUT) waveforms. The load facilitates fast contact testing when used in conjunction with the parators, 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 position of the exposed heat slug and the pin arrangement. The MAX9973G/MAX9974G parator outputs sink 8m A (typ), while the MAX9973H/MAX9974H parator outputs sink 16m A (typ). The devices are available in a 64-pin (10mm x 10mm x 1.00mm) TQFP-EP package with an exposed paddle on top (MAX9973) or bottom (MAX9974) for heat removal. Power dissipation is only 700m W 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 Features a temperature monitor output. o 600Mbps at 3V High Speed o 700m W...
