AVR220 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.
