MC14532B
8−Bit Priority Encoder
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
(Q0 thru Q2), one group select (GS) and one enable output (E

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
1. Temperature Derating:
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
high−impedance circuit. For proper operation, V
