8-BIT SHIFT REGISTERS The SN54L/ 74LS166 is an 8-Bit Shift Register.
Designed with all inputs buffered, the drive requirements are lowered to one 54/ 74LS standard load.
By utilizing input clamping diodes, switching transients are minimized and system design simplified.
The LS166 is a parallel-in or serial-in, serial-out shift register and has a complexity of 77 equivalent gates 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...
