The MAX9977 quad, low-power, high-speed, pin-elec-

tronics driver includes, for each channel, a three-level

pin driver. 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 MAX9977 provides high-speed, differential control

inputs with internal 50Ω (100Ω LVDS) termination resistors

that allow compatibility with 1.8V and 3.5V terminated

0.4V

required on the circuit board. The MAX9977AD has no

internal termination.

A 3-wire, low-voltage, CMOS-compatible serial interface

programs the low-leakage and tri-state/terminate opera-

tional configurations of the MAX9977.

The MAX9977’s operating range is -1.5V to +6.5V (con-

sult factory for other operating ranges), and features a

maximum power dissipation of only 0.8W per channel.

The device is available in a 100-pin, 14mm x 14mm

x 0.1mm body, and 0.5mm pitch TQFP. An exposed

8mm x 8mm die pad on the top of the package facili-

tates efficient heat removal. The device is specified to

operate with an internal die temperature of +60°C to

+100°C, and features a die temperature monitor output.
