MC14555B, MC14556B Dual Binary to 1-of-4 Decoder/Demultiplexer The MC14555B and MC14556B are constructed with complementary MOS (CMOS) enhancement mode devices. Each Decoder/Demultiplexer has two select inputs (A and B), an active low MC14555B, MC14556B TRUTH TABLE BLOCK DIAGRAM MC14555B MC14556B Inputs Outputs Enable Select MC14555B MC14556B Q0 4 Q0 4 2 2 A A E B A Q3 Q2 Q1 Q0 Q3Q2Q1Q0 Q1 5 Q1 5 3 B 3 B 0 0 0 0 0011 110 Q2 6 Q2 6 0 0 1 0 0101 101 1 E 1 E Q3 7 Q3 7 0 1 0 0 1001 011 0 1 1 1 0000 111 1 X X 0 0001 111 Q0 12 Q0 12 14 14 A A X = Dont Care Q1 11 Q1 11 13 B 13 B Q2 10 Q2 10 15 E 15 E Q3 9 Q3 9 V = PIN 16 DD V = PIN 8 SS ELECTRICAL CHARACTERISTICS (Voltages Referenced to V ) SS 55C 25C 125C Typ V DD (Note 2) Vdc Min Max Min Max Min Max Characteristic Symbol Unit Output Voltage 0 Level V 5.0 0.05 0 0.05 0.05 Vdc OL V = V or 0 10 0.05 0 0.05 0.05 in DD 15 0.05 0 0.05 0.05 1 Level V 5.0 4.95 4.95 5.0 4.95 Vdc OH V = 0 or V 10 9.95 9.95 10 9.95 in DD 15 14.95 14.95 15 14.95 Input Voltage 0 Level V Vdc IL (V = 4.5 or 0.5 Vdc) 5.0 1.5 2.25 1.5 1.5 O (V = 9.0 or 1.0 Vdc) 10 3.0 4.50 3.0 3.0 O (V = 13.5 or 1.5 Vdc) 15 4.0 6.75 4.0 4.0 O 1 Level V Vdc IH (V = 0.5 or 4.5 Vdc) 5.0 3.5 3.5 2.75 3.5 O (V = 1.0 or 9.0 Vdc) 10 7.0 7.0 5.50 7.0 O (V = 1.5 or 13.5 Vdc) 15 11 11 8.25 11 O Output Drive Current I mAdc OH (V = 2.5 Vdc) Source 5.0 3.0 2.4 4.2 1.7 OH (V = 4.6 Vdc) 5.0 0.64 0.51 0.88 0.36 OH (V = 9.5 Vdc) 10 1.6 1.3 2.25 0.9 OH (V = 13.5 Vdc) 15 4.2 3.4 8.8 2.4 OH (V = 0.4 Vdc) Sink I 5.0 0.64 0.51 0.88 0.36 mAdc OL OL (V = 0.5 Vdc) 10 1.6 1.3 2.25 0.9 OL (V = 1.5 Vdc) 15 4.2 3.4 8.8 2.4 OL Input Current I 15 0.1 0.00001 0.1 1.0 Adc in Input Capacitance, (V = 0) C 5.0 7.5 pF in in Quiescent Current (Per Package) I 5.0 5.0 0.005 5.0 150 Adc DD 10 10 0.010 10 300 15 20 0.015 20 600 Total Supply Current (Notes 3, 4) I 5.0 I = (0.85 A/kHz) f + I Adc T T DD (Dynamic plus Quiescent, 10 I = (1.70 A/kHz) f + I T DD Per Package) 15 I = (2.60 A/kHz) f + I T DD (C = 50 pF on all outputs, all L buffers switching) Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. 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 25C. 4. To calculate total supply current at loads other than 50 pF: I (C ) = I (50 pF) + (C 50) Vfk where: I is in A (per package), C in pF, T L T L T L V = (V V ) in volts, f in kHz is input frequency, and k = 0.002.
