1 standard ics dual 4-channel analog multiplexer / demultiplexer BU4052BC / BU4052BCf / BU4052BCfv the BU4052BC, BU4052BCf, and BU4052BCfv are multiplexers / demultiplexers capable of selecting and combin- ing analog signals and digital signals with a configuration of 4 ch 2. inhibit signals and control signals are used to turn on the switch of the corresponding channel. in addition, even if the logical amplitude (v dd -v ss ) of the control signal is low, signals with a large amplitude (v dd -v ee ) can be switched. in addition, as each switch has a low on resistance, it can be connected to a low impedance circuit. block diagram y 0 1 y 2 2 common y 3 y 3 4 y 1 5 inh 6 v ee 7 v ss 8 16 15 14 13 12 11 10 9 v dd x 2 x 1 x x 0 x 3 a b y 0 b y out / in inh v ee x out / in a common y 2 y 3 y 1 x 2 x 1 x 0 x 3
