NCS2250数据手册ONSEMI中文资料规格书

描述 Description

The NCS2250 low voltage comparators feature fast response time and rail-to-rail input and output. The extended common mode input voltage range allows inputs 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 and are offered in SOT23-5 and SC70-5 packages. Automotive qualified devices are also available, denoted by the NCV prefix.
