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.
