The ALS165 are parallel-load 8-bit serial shift  
registers that, when clocked, shift the data toward

serial (Q and Q ) outputs. Parallel-in access to  
H
H
each stage is provided by eight individual direct  
data (AH) inputs that are enabled by a low level  
at the shift/load (SH/LD) input. The ALS165 have  
a clock-inhibit function and complemented serial  
outputs.

Clocking is accomplished by a low-to-high  
transition of the clock (CLK) input while SH/LD is  
held high and the clock inhibit (CLK INH) input is  
held low. The functions of CLK and CLK INH are  
interchangeable. Since a low CLK and a  
low-to-high transition of CLK INH also  
accomplishes clocking, CLK INH should be  
changed to the high level only while CLK 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 independently of the  
levels of the CLK, CLK INH, or serial (SER) inputs.
