It`s Free AVR520 harman/kardon 8-channel analog multiplexer / demultiplexer BU4051BC / BU4051BCF / BU4051BCFV The BU4051BC, BU4051BCF and BU4051BCFV are analog multiplexers / demultiplexers which use three-input digi- tal signals for control via an 8-channel analog switch. These products feature high on / off output voltage ratio and low crosstalk between analog switches.
Page 97 It`s Free AVR520 harman/kardon 8-bit compatible shift / store register BU4094BC / BU4094BCF / BU4094BCFV The BU4094BC, BU4094BCF, and BU4094BCFV are shift / store registers, each consisting of an 8-bit register and an 8-bit latch. As the data in the shift register can be latched by an asynchronous strobe input, it is possible to hold the output in the data transfer mode.
