| Standard ICs Quad 2-channel analog multiplexer / demultiplexer BU4551B / BU4551BF / BU4551BFV The BU4551B, BU4551BF, and BU4551BFV are multiplexers / demultiplexers capable of selecting and combining analog signals and digital signals with a configuration of 2 ch x 4. Control signals are used to turn on the switch of the corresponding channel. In addition, even if the logical amplitude (VDD-VSS) of the control signal is low, signals with a large amplitude (VDD-VEE) can be switched. In addition, as each switch has a low ON resistance, it can be connected to a low impedance circuit. *Logic circuit diagram VDD (16) CONT (9) Level Converter Control *Block diagram W1 X0 1 2 W1 X0 X1 X (14)W Y (4) X (5) Y (13) Z Y0 6 5 4 X Y Y0 VEE CONTROL VEE 7 10 Y1 W0 W Z Z1 Z0 Y1 11 Z0 13 Z 16 VDD 15 W0 VSS VEE W1 X0 X1 Y0 (8) (7) (1) (2) (3) (6) X1 3 14 W W0 (15) 12 Z1 Y1 (10) Z0 (11) Z1 (12) VSS 8 9 CONTROL *Truth table CONTROL 0 1 ON W0 X0 Y0 Z0 W1 X1 Y1 Z1 1 Standard ICs BU4551B / BU4551BF / BU4551BFV *Absolute maximum ratings (VSS = 0V, Ta = 25C) Parameter Power supply voltage 1 Power supply voltage 2 Power dissipation Operating temperature Storage temperature Input voltage Symbol VDD - VEE VDD Pd Topr Tstg VIN Limits - 0.3 ~ + 18 - 0.3 ~ + 18 1000 (DIP), 500 (SOP), 400 (SSOP) - 40 ~ + 85 - 55 ~ + 150 - 0.3 ~ VDD + 0.3 Unit V V mW C C V *Electrical characteristics otherwise noted, Ta = 25C, VEE = VSS = 0V) DC characteristics (unless Parameter Symbol Min. 3.5 VIH 7.0 11.0 -- Input low-level voltage Input high-level current Input low-level current VIL -- -- IIH IIL -- -- -- ON resistance RON -- -- -- ON resistance deflexion OFF-channel leakage current Static current dissipation RON -- -- -- IOFF -- -- IDD -- -- Typ. -- -- -- -- -- -- -- -- -- -- -- 25 10 5 -- -- -- -- -- Max. -- -- -- 1.5 3.0 4.0 0.3 - 0.3 1100 500 280 -- -- -- 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 -- -- Fig.3 -- Fig.2 VIN = VDD / 2 Fig.2 VIH = 15V VIL = 0V Fig.1 Fig.1 -- Fig.1 -- Fig.1 Conditions Measurement circuit Input high-level voltage 2 Standard ICs BU4551B / BU4551BF / BU4551BFV Switching characteristics (unless otherwise noted, Ta = 25C, VEE = VSS = 0V, RL = 10 k, CL = 50pF) Parameter Symbol Min. -- Propagation delay time Switch INOUT tPLH tPHL -- -- -- Propagation delay time CONTOUT tPZH tPHZ -- -- -- Propagation delay time CONTOUT Max. propagation frequency Feedthrough attenuation Sine wave distortion Input capacitance (control) Input capacitance (switch) tPZL tPLZ fMax.
