General Description
The DM74ALS165 is an 8-bit serial register that, when
clocked, shifts the data toward serial output, Q
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 function and a complemented serial output, Q
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 accomplish clocking, CLK INH should be changed
to the high level only while the CLK input is HIGH. Paral-
lel loading is inhibited when SH/LD is held HIGH. The
parallel inputs to the register are enabled while SH/LD is
LOW independently of the levels of CLK, CLK INH, or
SER inputs.
