MC14532B
8−Bit Priority Encoder
The MC14532B is constructed with complementary MOS (CMOS)
enhancement mode devices. The primary function of a priority
encoder is to provide a binary address for the active input with the
highest priority. Eight data inputs (D0 thru D7) and an enable input
(E
are provided. Five outputs are available, three are address outputs
in)
(Q0 thru Q2), one group select (GS) and one enable output (E

This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
