_______________Detailed Description
The MAX4111/MAX4121/MAX4221 video switches are
manufactured with Maxim’s proprietary, ultra-high fre-
quency, complementary bipolar process that yields
high bandwidth and low capacitance. Make-before-
break switching is used to reduce noise and glitches,
even when switching from part to part in large arrays.
The input buffers provide a constant high input imped-
ance, and prevent the make-before-break action from
feeding back to the input.
The design of the switching mechanism limits the
inevitable glitch to less than 13mVp-p. In addition, the
glitch pulse is positive to avoid confusion with negative
sync pulses.
Unity-gain buffers isolate other inputs from the switch-
ing action of large multiplex arrays. These buffers can
drive 5k
resistive loads. In addition, these devices
drive capacitive loads without oscillation. Load capaci-
tance is limited only by system bandwidth require-
ments.
The MAX4111/MAX4121/MAX4221 do not contain
buffer latches. The digital inputs are transparent.

Logic Input. Output Enable for the 1x1, 2x1 switches. A logic high on this
pin enables the output. A logic low causes the output to assume a high-
impedance state, and reduces supply current.
