1 _{Typical values are defined at TA = +25°C and VDD = 12V, unless otherwise specified}
2 _{Guaranteed by design and verified by characterization, not production tested}
3 _{RPU and VPU are respectively the external pull-up resistor and pull-up power supply}
4 _{If the Output is in Current Limitation longer than tCLON the Output is switched off in high-impedance state. The Output returns back in active state at next reaching of BOP or after}
tCLOFF time interval
5 _{The Delay Time is the time from magnetic threshold reached to the start of the output switching}
6 _{Output jitter is the unpredictable deviation of the Delay time}
7 _{Maximum switching frequency corresponds to the maximum frequency of the applied magnetic field which is detected without loss of pulses}
8 _{The Power-On Time represents the time from reaching VDD = VPOR to the first refresh of the output (first valid output state)}
9 _{Power-On Slew Rate is not critical for the proper device start-up}
10 _{TPROT and TREL are the corresponding junction temperature values.}
