MC14532BDG ON Semiconductor

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

Product performance may not be indicated by the Electrical Characteristics if operated under different conditions. 2. Data labelled Typ is not to be used for design purposes but is intended as an indication of the ICs potential performance. 3. The formulas given are for the typical characteristics only at 25 C. 4. To calculate total supply current at loads other than 50 pF: I (C ) = I (50 pF) + (C 50) Vfk T L T L where: I is in A (per package), C in pF, V = (V V ) in volts, f in kHz is input frequency, and k = 0.005.
