74HC164
8-Bit Serial-In and Parallel-Out Shift Register
GENERAL DESCRIPTION
FEATURES
The 74HC164 is an 8-bit serial-in and parallel-out shift
register which can accept a wide supply voltage range
from 2.0V to 5.5V.
● Wide Operating Voltage Range: 2.0V to 5.5V
● +5.2mA/-5.2mA Output Current
● CMOS Low Power Consumption
● Gated Serial Data Inputs
This device provides gated serial inputs (DSA and DSB)
and parallel data outputs (Q0 to Q7). DSA and DSB
support serial data entry, where either input can allow
data to enter through another input as an active high
input. CP is a clock input. When the device is on
low-to-high clock transition of the CP, data can be
● Asynchronous Master Reset Input
● -40℃ to +125℃ Operating Temperature Range
● Available in Green SOIC-14 and TSSOP-14

from the other inputs. When MR is held low, it can
make the register clear and all outputs must be low
level. The clamp diodes of inputs allow the use of
current limiting resistors to connect inputs to the
voltage exceeding supply voltage.
