The UT54ACS165E is an 8-bit serial shift register that, when clocked,
shifts the data toward serial output Q
H
. Parallel-in access to each stage
is provided by eight individual data inputs that are enabled by a low
level at the SH/LD input. The devices feature a clock inhibit function
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 accomplish clocking, CLK INH should be changed to the high
level only while the CLK input is high. Parallel loading is disabled
when SH/LD is held high. Parallel inputs to the registers are enabled
while SH/LD is low independently of the levels of CLK, CLK INH or
SER inputs.
The device is characterized over the full military temperature range of
-55°C to +125°C.
Note:
1. Q
n
= The state of the referenced output one setup time prior to the Low-to-
High clock transition.
