... The fan tachometer is designed for fan speed output as open-drain output with a built-in pull-up resistor about 100KΩ and these devices are designed for different applications, ST1114E is for 4 poles fan application, ST1114K is for 8 poles fan application and ST1114P is for rotation detection output. With suitable output pull up resistance, this fan tachometer output can be used directly with bipolar or MOS logic for motor speed monitoring/control ...

... Application Notes The FGR pin is an open-drained output with built-in pull-up resistor about 100K Ω and outputs the same frequency with HIN pin for ST1114E, the half frequency of HIN pin for ST1114K, and rotation detection result for ST1114P. An additional resistor can be used to pull up the FGR voltage to the appropriate level which depends on the voltage level of the monitoring/control system ...
