MC14532B Datasheet | Motorola Semiconductor

MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC14532B 8-Bit Priority Encoder The MC14532B is constructed with plementary 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 MAXIMUM RATINGS- (Voltages Referenced to VSS) Symbol VDD Parameter DC Supply Voltage L SUFFIX CERAMIC CASE 620 ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ Value Unit V V m A m W - 0.5 to + 18.0 ± 10 500 - 65 to + 150 260 Vin, Vout Iin, Iout PD Tstg TL Input or Output Voltage (DC or Transient) Input or Output Current (DC or Transient), per Pin Power Dissipation, per Package† Storage Temperature Lead Temperature (8- Second Soldering) - 0.5 to VDD + 0.5 - Maximum Ratings are those values beyond which damage to the device may occur. †Temperature Derating: Plastic “P and D/DW” Packages: - 7.0 m W/_ C From 65_ C To 125_ C Ceramic “L” Packages: - 12 m W/_ C From 100_ C To 125_ C TRUTH TABLE Input Ein 0 1 1 1 1 1 1 1 1 1 D7 X 0 1 0 0 0 0 0 0 0 D6 X 0 X 1 0 0 0 0 0 0 D5 X 0 X X 1 0 0 0 0 0 D4 X 0 X X X 1 0 0 0 0 D3 X 0 X X X X 1 0 0 0 D2 X 0 X X X X X 1 0 0 D1 X 0 X X X X X X 1 0 D0 X 0 X X X X X X X 1 X = Don’t Care w w .D w t a GS 0 0 1 1 1 1 1 1 1 1 S a Q2 0 0 1 1 1 1 0 0 0 0 Q1 0 0 1 1 0 0 1 1 0 0 e h _C _C t e U 4 ORDERING INFORMATION MC14XXXBCP MC14XXXBCL MC14XXXBD Plastic Ceramic SOIC .c D4 D5 D6 D7 1 2 3 4 5 6 7 8 m o 16 15 14 13 12 11 10 9 P SUFFIX PLASTIC CASE 648 D SUFFIX SOIC CASE 751B TA = - 55° to 125°C for all packages.
