MAX9967 19-3195 Rev 1 2/05 Dual, Low-Power, 500Mbps ATE Driver/Comparator with 35mA Load General Description Features The MAX9967 dual, low-power, high-speed, pin electron- Low Power Dissipation: 1.15W/Channel (typ) ics driver/comparator/load (DCL) IC includes, for each High Speed: 500Mbps at 3V P-P channel, a three-level pin driver, a dual comparator, vari- able clamps, and an active load. The driver features a Programmable 35mA Active-Load Current wide voltage range and high-speed operation, includes Low Timing Dispersion high-impedance and active-termination (3rd-level drive) modes, and is highly linear even at low-voltage swings. Wide -1.5V to +6.5V Operating Range The dual comparator provides low dispersion (timing Active Termination (3rd-Level Drive) variation) over a wide variety of input conditions. The clamps provide damping of high-speed device-under- Low Leakage Mode: 60nA test (DUT) waveforms when the device is configured as a Integrated Clamps high-impedance receiver. The programmable load sup- plies up to 35mA of source and sink current. The load Interfaces Easily with Most Logic Families facilitates contact/continuity testing, at-speed parametric Integrated PMU Connection testing of IOH and IOL, and pullup of high-output-imped- ance devices. Digitally Programmable Slew Rate The MAX9967A provides tight matching of gain and off- Internal Termination Resistors set for the drivers, and offset for the comparators and active load, allowing reference levels to be shared Low Gain and Offset Error across multiple channels in cost-sensitive systems. Use the MAX9967B for system designs that incorporate independent reference levels for each channel. Ordering Information The MAX9967 provides high-speed, differential control PART TEMP RANGE PIN-PACKAGE inputs with optional internal termination resistors that are compatible with ECL, LVPECL, LVDS, and GTL. MAX9967ADCCQ* 0C to +70C 100 TQFP-EPR** ECL/LVPECL or flexible open-collector outputs with MAX9967AGCCQ* 0C to +70C 100 TQFP-EPR** optional internal pullup resistors are available for the MAX9967ALCCQ 0C to +70C 100 TQFP-EPR** comparators. These features significantly reduce the MAX9967AMCCQ* 0C to +70C 100 TQFP-EPR** discrete component count on the circuit board. MAX9967AQCCQ* 0C to +70C 100 TQFP-EPR** A 3-wire, low-voltage, CMOS-compatible serial interface MAX9967ARCCQ* 0C to +70C 100 TQFP-EPR** programs the low-leakage, slew-rate limit, and tri- state/terminate operational configurations of the MAX9967BDCCQ 0C to +70C 100 TQFP-EPR** MAX9967. MAX9967BGCCQ 0C to +70C 100 TQFP-EPR** The MAX9967s operating range is -1.5V to +6.5V with MAX9967BLCCQ 0C to +70C 100 TQFP-EPR** power dissipation of only 1.15W per channel. The MAX9967BMCCQ 0C to +70C 100 TQFP-EPR** device is available in a 100-pin, 14mm x 14mm body, MAX9967BQCCQ* 0C to +70C 100 TQFP-EPR** and 0.5mm pitch TQFP. An exposed 8mm x 8mm die MAX9967BRCCQ 0C to +70C 100 TQFP-EPR** pad on the top of the package facilitates efficient heat removal. The device is specified to operate with an *Future productcontact factory for availability. internal die temperature of +70C to +100C, and **EPR = Exposed pad reversed (TOP). features a die temperature monitor output.

Actual maximum allowable power dissipation is a function of 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.
