1 / 7 page © Semiconductor Components Industries, LLC, 2014 July, 2014 − Rev. 9 1 Publication Order Number: MC14532B/D 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 (Ein) are provided. Five outputs are available, three are address outputs (Q0 thru Q2), one group select (GS) and one enable output (Eout). Features • 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 • NLV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable • This Device is Pb−Free and is RoHS Compliant MAXIMUM RATINGS (Voltages Referenced to VSS) Rating Symbol Value Unit DC Supply Voltage Range VDD − 0.5 to +18.0 V Input or Output Voltage Range (DC or Transient) Vin, Vout −0.5 to VDD + 0.5 V Input or Output Current (DC or Transient) per Pin Iin, Iout ±10 mA Power Dissipation, per Package (Note 1) PD 500 mW Ambient Temperature Range TA − 55 to +125 °C Storage Temperature Range Tstg − 65 to +150 °C Lead Temperature (8 Sec Soldering) TL 260 °C Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. 1. Temperature Derating: “D/DW” Package: –7.0 mW/ _C From 65_C To 125_C 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 high−impedance circuit. For proper operation, Vin and Vout should be constrained to the range VSS ≤ (Vin or Vout) ≤ VDD. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open.
