description/ordering information  
CLK INH  
CLK  
F
This parallel-in or serial-in, serial-out register  
features gated clock (CLK, CLK INH) inputs and an  
overriding clear (CLR) input. The parallel-in or  
serial-in modes are established by the shift/load  
E
GND  
CLR  
(SH/LD) input. When high, SH/LD enables the serial (SER) data input and couples the eight flip-flops for serial  
shifting with each clock (CLK) pulse. When low, the parallel (broadside) data inputs are enabled, and  
synchronous loading occurs on the next clock pulse. During parallel loading, serial data flow is inhibited.  
Clocking is accomplished on the low-to-high-level edge of CLK through a 2-input positive-NOR gate, permitting  
one input to be used as a clock-enable or clock-inhibit function. Holding either CLK or CLK INH high inhibits  
clocking; holding either low enables the other clock input. This allows the system clock to be free running, and  
the register can be stopped on command with the other clock input. CLK INH should be changed to the high  
level only when CLK is high. CLR overrides all other inputs, including CLK, and resets all flip-flops to zero.
