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.
