MAX9142EKA+T General Description

The MAX9140/MAX9141 are single and the MAX9142/

MAX9144 are dual/quad high-speed comparators optimized

for systems powered from a 3V or 5V supply. The MAX9141

features latch enable and device shutdown. These devices

combine high speed, low power, and rail-to-rail inputs.

Propagation delay is 40ns, while supply current is only

150μA per comparator
