Overview
The MC14532B, specifically the MC14532BDG package, is an 8-Bit Priority Encoder produced by onsemi. This device is constructed with complementary MOS (CMOS) enhancement mode devices. Its primary function is to provide a binary address for the active input with the highest priority. The encoder features eight data inputs (D0 through D7) and an enable input (Ein), along with five outputs: three address outputs (Q0 through Q2), one group select (GS), and one enable output (Eout).
