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 (D
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 Q
the two data inputs (D
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. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability .
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
