DESCRIPTION

The LMH7322 is a dual comparator with 700 ps

propagation delay, low dispersion of 75 ps and an

input voltage range that extends from VCC-1.5V to

VEE. The devices can be operated from a wide supply

voltage range of 2.7V to 12V. The adjustable

hysteresis adds flexibility and prevents oscillations. Both the outputs and latch inputs of the LMH7322 are

RSPECL compatible. When used in combination with

a VCCO supply voltage of 2.5V the outputs have LVDS

compatible levels.

The LMH7322 is available in a 24-pin WQFN

package.
