iC-DXC3

DIGITAL SENSOR I/O DRIVER

Rev B2, Page 8/12

OPERATING MODES

The iC-DXC3 can be operated in high-side (PNP), low-

side (NPN) and push-pull (PP) switch mode. Figure 4

shows the high-side operation where NIN pin must be

kept low and the OE pin controls the switch. Figure 5

shows the low-side operation where NIN pin must be

kept high and the OE pin controls the switch. Figure 6

shows the push-pull operation where OE pin must be

kept high and the NIN pin controls the switch. If the

OUT signal differs from what declared in tables 4, 5

and 6 (due to external forcing) for more than 14 µs (cf.

Electrical Characteristics No. 510), this event will be

signalled by a low level at MON output.
