The NCS2250 and NCS2252 low voltage comparators feature fast

response time and rail?to?rail input and output. The extended

common mode input voltage range allows input signals 200 mV above

and below the rails, allowing voltage detection at ground or the supply.

A propagation delay of 50 ns with a 100 mV overdrive makes this

comparator suitable for applications requiring faster response times.

These single channel devices are available with a complementary

push?pull output in the NCS2250 or with an open drain output in the

NCS2252. Both options are offered in TSOP?5 (SOT23?5) and

SC?88A (SC70?5) packages. Automotive qualified devices are also

available, denoted by the NCV prefix.
