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 (Ein)are provided. Five outputs are available, three are address outputs (Q0 thru Q2), one group select (GS) and one enable output (Eout).

•Diode Protection on All Inputs
•Supply Voltage Range = 3.0 Vdc to 18 Vdc
•Capable of Driving Two Low–power TTL Loads or One Low–Power
Schottky TTL Load over the Rated Temperature Range
