LMH7324
Quad 700 PS High Speed Comparator with RSPECL
Outputs
General Description
The LMH7324 is a quad comparator with 700 ps propagation
delay and low dispersion of less then 20 ps for a supply volt-
age of 5V. The input voltage range extends from VCC−2V to
VEE−200 mV The devices can be operated from a wide supply
voltage range of 5V to 12V.
The outputs of the LMH7324 are RSPECL compatible. The
LMH7324 is available in a 32-Pin LLP package.

Input for analog voltages between 200 mV below VEE and 2V below
VCCI.
All four VEE pins are circular connected together via two antiparallel
diodes. (see Figure 4)

This supply pin is independent of the supply for the output stage.
VCCI and VCCO share the same ground pin VEE.
This supply pin is independent of the supply for the input stage. This
allows output levels of different logic families.
Output levels are determined by the choice of VCCOC.
