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
