Product Description

CD4078BPWR combines an eight-input OR function with its complementary NOR output, allowing either polarity without an extra inverter. The CD4000B operating supply range also supports higher-voltage CMOS logic.

The 20 V headline is an absolute-maximum rating; recommended operation stops at 18 V. Delay and drive capability vary with supply, so the retained 10 V timing point should not be treated as a 5 V specification.
