SL74LS164
8-Bit Serial-Input/Parallel-Output
Shift Register
This 8-bit shift register features gated serial inputs and an
asynchronous reset. The gated serial inputs (A and B) permit complete
control over incoming data as a low at either (or both) input(s) inhibits
entry of the new data and resets the first flip flop to the low level at the
next clock pulse. A high level input enables the other input which will
then determine the state of the first flip-flop. Data at the serial inputs
may be changed while the clock is high or low, but only information
meeting the setup requirements will be entered clocking occurs or the
low-to-high level transition of the clock input. All inputs are diode-
clamped to minimize transmission-line effects.
• Gated (Enable/Disable) Serial Inputs
• Fully Buffered Clock and Serial Inputs
• Asynchronous Clear
