TECHNICAL DATA KK74HC166A 8-Bit Serial or Parallel-Input/ Serial-Output Shift Register High-Performance Silicon-Gate CMOS The KK74HC166A is identical in pinout to the LS/ALS166.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.
This device is a parallel-in or serial-in, serial-out shift register with gated clock inputs and an overriding clear input.
The shift/load input establishes the parallel-in or serial-in mode.
When high, this input enables the serial data input and couples the eight flip-flops for serial shifting with each clock pulse.
Synchronous loading occurs on the next clock pulse when this is low and ...
