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 20 ps for a supply voltage of 5V.
The input voltage range extends 200 mV below the negative
supply. This enables the LMH7324 to ground sense even
when operating on a single power supply. The device oper-
ates from a wide supply voltage range from 5V to 12V, which
allows for a wide input voltage range. However, if a wide input
voltage range is not required, operating from a single-ended
5V supply results in a significant power savings, and less heat
dissipation.
The outputs of the LMH7324 are RSPECL compatible and
can also be configured to create LVDS levels. The LMH7324
operates over the industrial temperature range of −40°C to
125°C. The LMH7324 is available in a 32-Pin LLP package.
