DESCRIPTION
The 74LV164 is a low-voltage Si-gate CMOS device and is pin and
function compatible with the 74HC/HCT164.
The 74LV164 is an 8-bit edge-triggered shift register with serial data
entry and an output from each of the eight stages. Data is entered
serially through one of two inputs (Dsa or Dsb); either input can be
used as an active HIGH enable for data entry through the other
input. Both inputs must be connected together or an unused input
must be tied HIGH.
Data shifts one place to the right on each LOW-to-HIGH transition of
the clock (CP) input and enters into Q0, which is the logical AND of
the two data inputs (Dsa, Dsb) that existed one set-up time prior to
the rising clock edge.
A LOW on the master reset (MR) input overrides all other inputs and
clears the register asynchronously, forcing all outputs LOW.

Notes 1 and 2
NOTES:
1. CPD is used to determine the dynamic power dissipation (PD in µW)
PD = CPD VCC2 x fi )S (CL VCC2 fo) where:
fi = input frequency in MHz; CL = output load capacitance in pF;
fo = output frequency in MHz; VCC = supply voltage in V;
S (CL VCC2 fo) = sum of the outputs.
2. The condition is VI = GND to VCC
