Description

The MAX9961/MAX9962 dual, low-power, high-speed, pin electronics driver/comparator/load (DCL) ICs include, 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 2mA of source and sink current. The load facilitates contact/continuity testing and pullup of high-output-impedance devices.

The MAX9961A/MAX9962A provide tight matching of offset for the drivers and the comparators, allowing reference levels to be shared across multiple channels in cost-sensitive systems. Use the MAX9961B/MAX9962B for system designs that incorporate independent reference levels for each channel.

The MAX9961/MAX9962 provide high-speed, differential control inputs compatible with LVPECL, LVDS, and GTL. The MAX9961/MAX9962 are available with optional internal termination resistors. The open-collector comparator outputs are available with or without internal pullup resistors. The optional internal resistors significantly reduce the discrete component count on the circuit board.

A 3-wire, low-voltage, CMOS-compatible serial interface programs the low-leakage, slew-rate limit, and tri-state/ terminate operational configurations of the MAX9961/MAX9962.

The MAX9961/MAX9962s' operating range is -1.5V to +6.5V with power dissipation of only 900mW per channel. The devices are available in a 100-pin, 14mm x 14mm body, and 0.5mm pitch TQFP. An exposed 8mm x 8mm die pad on the top (MAX9961) or bottom (MAX9962) of the package facilitates efficient heat removal. The device is specified to operate with an internal die temperature of +70°C to +100°C, and features a die temperature monitor output.
