| Standard ICs 8-channel analog multiplexer / demultiplexer BU4051BC / BU4051BCF / BU4051BCFV The BU4051BC, BU4051BCF and BU4051BCFV are analog multiplexers / demultiplexers which use three-input digital signals for control via an 8-channel analog switch. These products feature high on / off output voltage ratio and low crosstalk between analog switches. *Block diagram X4 1 CHANNEL IN / OUT X6 COMMON OUT / IN 2 X4 X 3 4 X6 X X7 CHANNEL IN / OUT X5 5 X7 X5 INH INH 6 7 VEE C VEE 10 B 9 X2 X1 X0 X3 A B 11 A 13 X0 14 X1 CHANNEL IN / OUT 16 VDD 15 X2 12 X3 VSS 8 C *Logic circuit diagram VDD (16) INH (6) A (11) B (10) C (9) VSS (8) VEE (7) X0 (13) X1 (14) X2 (15) X3 (12) X4 (1) X5 (5) X6 (2) X7 (4) LEVEL CONVERTER *Truth table INH L A L H L H L H L H X B L L H H L L H H X C L L L L H H H H X ON SWITCH X0 X1 X2 X3 X4 X5 X6 X7 NONE L L L L X (3) COMMON BINARY TO 1 of 8 DECODER WITH INHIBIT L L L H X: Irrelevant 1 Standard ICs BU4051BC / BU4051BCF / BU4051BCFV *Absolute maximum ratings (Ta = 25C) Parameter Power supply voltage 1 Power supply voltage 2 Power dissipation Operating temperature Storage temperature Input voltage Symbol VDD VDD--VEE Pd Topr Tstg VIN Limits - 0.5 ~ + 20 - 0.5 ~ + 20 1000 (DIP), 500 (SOP), 400 (SSOP) - 40 ~ + 85 - 55 ~ + 150 - 0.5 ~ VDD + 0.5 Unit V V mW C C V *Electrical characteristics otherwise noted, Ta = 25C, VEE = VSS = 0V) DC characteristics (unless Parameter Symbol Min. 3.5 Input high-level voltage VIH 7.0 11.0 -- Input low-level voltage VIL -- -- Input high-level current Input low-level current IIH IIL -- -- -- RON resistance RON -- -- -- RON resistance deflexion RON -- -- OFF-channel leakage current IOFF -- -- -- Static current dissipation IDD -- -- Typ. -- -- -- -- -- -- -- -- -- -- -- 10 6 4 -- -- -- -- -- Max. -- -- -- 1.5 3.0 4.0 0.3 - 0.3 950 250 160 -- -- -- 0.3 - 0.3 5 10 15 A A A A V V Unit VDD (V) 5 10 15 5 10 15 15 15 5 10 15 5 10 15 15 15 5 10 15 VI = VDD or GND -- -- VIN = VDD / 2 VIH = 15V VIL = 0V -- -- Conditions 2 Standard ICs BU4051BC / BU4051BCF / BU4051BCFV Switching characteristics (unless otherwise noted, Ta = 25C, VEE = VSS = 0V, RL = 1k, CL = 50pF) Parameter Symbol Min. -- Propagation delay time CHANNEL INOUT tPLH tPHL -- -- -- Propagation delay time CONTOUT tPHZ, tPLZ tPZH, tPZL -- -- -- Propagation delay time INHIBITOUT Max. propagation frequency Feedthrough Sinewave distortion Input capacitance (control) Input capacitance (switch) tPHZ, tPLZ tPZH, tPZL fMax.
