Single Power Supply Quad Comparator
DESCRIPTION
R03DS0139EJ0100
Rev.1.00
2019.1.16
µPC177, µPC339 comparators are designed for single power supply operation. The features include low-
voltage operation, common-mode input voltage range from V-(GND) level, open-collector output and low
current consumption. Furthermore, these products can operate with both power supplies and can be widely
used for various voltage comparison application.
Depending on the usage and operating ambient temperature range, the μPC177 is design for communication
industries and μPC339 is design for general purposes.
In addition, compatible DC parameter selection for the comparators are available under special products.
Along with this series of lineup, the dual type comparators, μPC277 and 339 with the same circuit configuration
are also available.

【Note】1.
Note that reverse connections of the power supply may damage the ICs.
2. This is the input voltage range that can be applied to the input terminal without any characteristics degradation
or breakdown. It can be applied regardless of the supply voltage. Do not apply the voltage below V-(GND)-0.3V.
The comparator electrical characteristics will operate normally when the input voltage is operating within the
common-mode input voltage range.
3. Voltage range that can be applied externally to the output terminal without deteriorating or damage to the product.
It can be applied regardless of the power supply. Caution not to exceed the ratings, including transient
conditions such as when the power supply is ON/OFF.

【Note】
6. Direction of the input bias current flowing out of the IC due to first stage of IC consists of PNP transistors
In addition, the value of this item is the value when the differential amplifier circuit of the input stage is
balanced. It means that twice the current amount will flow to the lower potential terminal.
7. Current flowing through the internal circuit. This current flow regardless of the channel used.
8. Value when the input amplitude is 100mV and the overdrive is 5mV. The response time can be reduces by
increasing the overdrive value.
