Overview
TECHNICAL DATA IN74HC166 8-Bit Serial or Parallel-Input/ Serial-Output Shift Register High-Performance Silicon-Gate CMOS The IN74HC166 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 the parallel data inputs are enabled.
Serial data flow is inhibited during parallel loading.
Clocking is done on the low-to-high level edge of the clock pulse via a two input positive NOR gate, which permits one input to be used as a clock enable or clock inhibit function.
Clocking is inhibited when e...
