8-BIT PARALLEL-OUT SERIAL SHIFT RE4G0I0STERS
Description
The 74HC164 is a serial input 8-bit edge-triggered shift register that
has outputs from each of eight stages.
SERIAL DATA INPUT PINS
The serial input data is entered at pin SDA or pin SDB as these are
logically ANDED. Either input could be used as an active HIGH
enable with data entry on the other pin. If a single input is desired, the
pins can be tied together or the unused input can be tied HIGH.
DATA ENTRY
Data is shifted into Q0 from the serial input pins on each LOW to
HIGH transition of the CP pin. Also during the CP edge the data is
transferred from each Qn to Qn+1. The serial data on pins DSA and
DSB must be stable before and after the CP rising edge to meet the
set-up and hold timing requirements.

RESET
When asserted LOW the Master Reset ( MR ) pin sets all Qn to LOW.
This action does not depend on the condition of serial input or clock
pins. The MR must be asserted HIGH for a recovery time before the
next CP positive edge pulse.

5. All Q values are reset to LOW when MR goes low. MR is asynchronous and overrides all other signals.
6. Serial data supplied at DSA and DSB is ANDED and transferred to Q0 on positive edge of CP.

Notes:
7. Stresses beyond the absolute maximum may result in immediate failure or reduced reliability. These are stress values and device operation should
be within recommend values.
8. Input Voltage cannot exceed Vcc to the extent the maximum clamp current is exceeded.
