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 × 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 •Block diagram VDD (16) CONT (9) Level Converter Control W1 1 X0 2 16 VDD 15 W0 W1 VSS VEE X1 (8) 3 (7) W0 (15) W1 (1) X0 (2) X1 Y0 (3) (6) X 4 Y 5 (14)W (4) X (5) Y Y1 (10) Z0 (11) Y0 6 X0 W0 X1 W X Z Y Z1 Y0 Z0 Y1 VEE 14 W 13 Z 12 Z1 11 Z0 CONTROL (13) Z Z1 (12) VEE 7 10 Y1 VSS 8 9 CONTROL •Truth table CONTROL ON 0 W0 X0 Y0 1 W1 X1 Y1 Z1 Z0 1 Standard ICs BU4551B / BU4551BF / BU4551BFV •Absolute maximum ratings (V SS Parameter = 0V, Ta = 25°C) Symbol Limits Unit Power supply voltage 1 VDD - VEE – 0.3 ~ + 18 V Power supply voltage 2 VDD – 0.3 ~ + 18 V Power dissipation Pd 1000 (DIP), 500 (SOP), 400 (SSOP) mW Operating temperature Topr – 40 ~ + 85 °C Storage temperature Tstg – 55 ~ + 150 °C – 0.3 ~ VDD + 0.3 V VIN Input voltage characteristics •DCElectrical characteristics (unless otherwise noted, Ta = 25°C, V Parameter Input high-level voltage Input low-level voltage Symbol VIH VIL EE Min.
