General Description

The MAX9967 dual, low-power, high-speed, pin electronics driver/comparator/load (DCL) IC includes, for each channel, a three-level pin driver, a dual comparator, variable clamps, and an active load. 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. The dual comparator provides low dispersion (timing variation) over a wide variety of input conditions. The clamps provide damping of high-speed device-under-test (DUT) waveforms when the device is configured as a high-impedance receiver. The programmable load supplies up to 35mA of source and sink current. The load facilitates contact/continuity testing, at-speed parametric testing of IOH and IOL, and pullup of high-output-impedance devices.

The MAX9967A provides tight matching of gain and offset for the drivers, and offset for the comparators and active load, allowing reference levels to be shared across multiple channels in cost-sensitive systems. Use the MAX9967B for system designs that incorporate independent reference levels for each channel.
