1 MIC67 IttyBitty Comparator General Description The MIC67 is a precision voltage comparator with an offset voltage specification of maximum. The MIC67 is designed to operate from a single V to 6V power supply. Operation from split power supplies is also possible. Its low supply current drain is independent of the magnitude of the supply voltage. This comparator also features an input common-mode voltage range that includes ground. Inputs are protected against reverse polarity (input voltage less than V ) and ESD. The MIC67 has an open-collector output that directly interfaces with TTL, CMOS, and other types of logic. Several MIC67 outputs can be connected together for wired-or logic. The output also features an internal pullup current source that can be used instead of an external load in some applications.

A short circuit from OUT to V+ can cause excessive heating and damage the device. The maximum short circuit output current (OUT to V ) is approximately ma, independent of V V+.. Measured at the output switch point where V OUT.Vdc with R S = Ω, V+ = Vdc to Vdc, and over the full input common-mode range (Vdc to V+.Vdc).. The direction of input current is out of the device due to its PNP input.. The input common-mode voltage, V IN+, or V IN must not go below.v. The upper end of the common-mode voltage range is V+.V at C, but either or both inputs can go to +6Vdc without damage, independent of V V+.. The response time measured using a input step with overdrive. With greater overdrive, ns can be obtained. See Typical Characteristics. 6. Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the comparator will provide a proper output state. The low input voltage state must not be below.vdc (or.vdc below V V ). May 8 M
