The UT54ACS165 and the UT54ACTS165 are 8-bit serial shift regis-  
ters that, when clocked, shift the data toward serial output QH. 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 QH .

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  
theCLKandCLKINH(clockinhibit)inputsareinterchangeable. 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.
