1 standard ics triple 2-channel analog multiplexer / demultiplexer bu4053bc / bu4053bcf / bu4053bcfv the bu4053bc, bu4053bcf, and bu4053bcfv are multiplexers / demultiplexers capable of selecting and combin- ing analog signals and digital signals in a 2 ch 3 configuration. inhibit signals and control signals are used to turn on the switch corresponding to each of the channels. 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. also, as each switch has a low on resistance, it can be connected to a low impedance circuit. logic circuit diagram truth table v dd (16) inh (6) b (10) a (11) c (9) v ss (8) v ee (7) z 0 (5) z 1 (3) (4) z y 0 (2) y 1 (1) (15) y x 0 (12) x 1 (13) (14) x level converter binary to 1of 2 decoder with inh inh a b c on switch l lll lhll llhl lhhl lllh lhlh llhh l hhh h x x x none x 0 y 0 z 0 x 1 y 0 z 0 x 0 y 1 z 0 x 1 y 1 z 0 x 0 y 0 z 1 x 1 y 0 z 1 x 0 y 1 z 1 x 1 y 1 z 1 x: irrelevant block diagram y 1 1 y 0 2 z 1 3 z 4 z 0 5 inh 6 v ee 7 v ss 8 16 15 14 13 12 11 10 9 v dd y x x 1 x 0 a b c c z inh v ee y x a b y 0 z 1 z 0 y 1 x 1 x 0
