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.
