DM74ALS165
8-Bit Parallel In/Serial Out Shift Register
General Description
The DM74ALS165 is an 8-bit serial register that, when
clocked, shifts the data toward serial output, Q
H
. Parallel-in
access to each stage is provided by eight individual direct
data inputs that are enabled by a low level at the SH/LD
input. The DM74ALS165 also features a clock inhibit func-
tion and a complemented serial output, Q
H
.
Clocking is accomplished by a LOW-to-HIGH transition of
the CLK input while SH/LD is held HIGH and CLK INH is
held LOW. The functions of the CLK and CLK INH (clock
inhibit) inputs are interchangeable. Since a LOW CLK input
and a LOW-to-HIGH transition of CLK INH will also accom-
plish clocking, CLK INH should be changed to the high
level only while the CLK input is HIGH. Parallel loading is
inhibited when SH/LD is held HIGH. The parallel inputs to
the register are enabled while SH/LD is LOW indepen-
dently of the levels of CLK, CLK INH, or SER inputs.
