Comparator, High Speed,
50 ns, Low Voltage,
Rail-to-Rail
www.onsemi.com
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.

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
2. Refer to ELECTRICAL CHARACTERISTICS and APPLICATION INFORMATION for Safe Operating Area.
3. Applies to both single−supply and split−supply operation. Continuous short circuit operation at elevated ambient temperature can result in
exceeding the maximum allowed junction temperature of 150°C. Output currents in excess of
±50
mA over long term may adversely affect
reliability.
4. See APPLICATION INFORMATION for Safe Operating Area.
5. This device series incorporates ESD protection and is tested by the following methods:
− ESD Human Body Model tested per JEDEC standard JESD22−A114 (AEC−Q100−002)
− ESD Machine Model tested per JEDEC standard JESD22−A115 (AEC−Q100−003)
