Datasheet PC271, 311 R03DS0151EJ0100 Rev.1.00 2019.10.1 High Performance Comparator DESCRIPTION The PC271 and PC311 are high-performance general-purpose comparators that have the same input characteristics as general-purpose operational amplifiers and can directly drive standard logic circuits such as TTL, CMOS, and HNIL. Its power supply voltage range is flexible whereby it exhibits excellent characteristics not only in a 5 V single power supply but also in 15 V power supply which is equivalent to an operational amplifier. These products are equipped with a strobe terminal and input offset adjustment terminals, thus they can be widely applied to various voltage comparison circuits. Depending on the operating ambient temperature, the PC271 is suitable for communication application while the PC311 is suitable for general-purpose usage. FEATURES Input Offset Voltage 2 mV (TYP.) Input Bias Current 100 nA (TYP.) Pulse Response Time 200 ns (TYP.) Equipped with a Strobe Terminal, ideal for interfacing with logic circuits. Two output circuit formats are possible. (open collector, emitter follower) Large output current capacity to directly drive the LEDs and lamps.

Note that reverse connections of the power supply may damage the ICs. 2. The input terminal must be applied within the input voltage range to avoid deterioration or damaging the device characteristic. Do not exceed the ratings including during transient state such as ON/OFF, etc. The Comparator input voltage must operate within the electrical characteristics range of input common-mode voltage. 3. The output terminal and GND terminal must be apply within the output voltage range to avoid deteriorating or + damaging the device characteristic. The GND terminal must be less than V . Do not exceed the ratings including during transient state such as ON/OFF, etc. 4. This is the value at TA +25 C. De-rate value at -4.4 mW/ C when TA > 25 C. 5. Pay attention to output terminal current and GND terminal current. Please use the total loss and the de-rating value from Note 4. RECOMMENDED OPERATING CONDITIONS PARAMETER SYMBOL MIN. TYP. MAX.
