_______________General Description

The MAX4141 is a wideband 330MHz, 700V/µs 4x1

multiplexer optimized for high-definition, broadcast-

quality, composite (HDTV, NTSC, PAL, SECAM) video

switching arrays. The device includes four open-loop

buffer amplifiers with a 0.1dB gain flatness of 150MHz,

and enable and switch-control logic. The MAX4141

operates from ±5V supplies and features differential

phase and gain error of only 0.01°/0.01%. The ultra-low

switching glitch (less than 13mV) is positive to avoid

confusion with any sync pulses.

Ideal as a building block for large switch arrays, the

MAX4141 features a constant, high input impedance

and a disable function that puts the output into a high-

impedance state and reduces the operating current to

only 250µA. The open-loop architecture allows the out-

put to drive capacitive loads without oscillation.

Other key features include -66dB crosstalk (30MHz),

-74dB isolation (30MHz), less than 10mV offset voltage,

and a 110MHz full-power bandwidth (1.4Vp-p). The

MAX4141 is available in a 14-pin narrow SO package.
