DESCRIPTION
The M54/74HC164 is a high speed CMOS 8 BIT
SIPO SHIFT REGISTER fabricated in silicon gate
C2MOStechnology. Ithasthesamehighspeedperformance of LSTTL combined with true CMOS low
powerconsumption.
The HC164 is an 8 bit shiftregister with serialdata
entry and an output from each of the eight stages.
Data isentered serially through one oftwo inputs (A
or B), either of theseinputs canbeused asanactive
high enable for data entry through the other input.
An unused input must be high, or both inputs connected together. Each low-to-high transition on the
clock input shifts data one place to the right and
entersintoQA,thelogicNANDofthe twodata inputs
(A ⋅ B), the data that existed before the rising clock
edge. A low level on the clear input overrides all
otherinputsand clearstheregister asynchronously,
forcingall Q outputslow.
All inputs are equipped with protection circuits
against static discharge and transient excess voltage.
