    ... Application Information 1.0 INPUT COMMON-MODE VOLTAGE RANGE At supply voltages of 2.7V, 5V and 15V, the SM72375 has an input common-mode voltage range (CMVR) which exceeds both supplies the case of operational amplifiers, CMVR is defined by the V shift of the comparator over the com- OS mon-mode range of the device. A common-mode rejection ratio (CMRR, defined as Δ ...

    ... Typical Applications UNIVERSAL LOGIC LEVEL SHIFTER The output of the SM72375 is the uncommitted drain of the output NMOS transistor. Many drains can be tied together to provide an output OR'ing function. An output pullup resistor can be connected to any available power supply voltage with- in the permitted power supply range. ...
