MAX9142/MAX9144 40ns, Low-Power, 3V/5V, Rail-to-Rail
Single-Supply Comparators General Description Features 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.
The input common-mode range of the devices extends beyond
both power-supply rails. The outputs pull to within 0.3V of
either supply rail without external pullup circuitry, making these
devices ideal for interface with both CMOS and TTL logic. All
input and output pins can tolerate a continuous short-circuit
fault condition to either rail. Internal hysteresis ensures clean
output switching, even with slow-moving input signals. ●● Fast, 40ns Propagation Delay (10mV Overdrive)
