LMH7322 Dual 700 ps High Speed Comparator with RSPECL Outputs

Check for Samples: LMH7322

FEATURES

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 V_CC-1.5V to

V_EE. 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 V_CCOsupply voltage of 2.5V the outputs have LVDS

compatible levels.

•

(V_CCI= +5V, V_CCO= +5V)

Propagation Delay 700 ps

Overdrive Dispersion 20 mV-1V 75 ps

Fast Rise and Fall Times 160 ps

Wide Supply Range 2.7V to 12V

Input Common Mode Range Extends 200 mV
