UNISONIC TECHNOLOGIES CO., LTD U74HC4094 CMOS IC 8-STAGE SHIFT & STORE BUS REGISTER DESCRIPTION SOP-16 The U74HC4094 consists of an 8-stage shift register and an 8-stage D-type latch with 3-stage parallel outputs. Data is shifted serially through the shift register on the positive-going clock transition of the input singal. The output of the last stage QS1 can be used to cascade several devices. The output of QS1 is transferred to a second output(QS2) on the following negative-going clock transition of the input singal. The data of each stage of the shift register is provided with a latch whose data on the negative going transition of the Strobe input signal. When the strobe input is held high, data propagates through the latch to a 3-state output buffer. The buffer is enabled when Output Enable input is taken high.
