SN74LS166

8-Bit Shift Registers

The SN74LS166 is an 8-Bit Shift Register. Designed with all inputs

buffered, the drive requirements are lowered to one 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 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 either of the clock inputs are held high,

holding either input low enables the other clock input. This will allow

the system clock to be free running and the register stopped on

command with the other clock input. A change from low-to-high on

the clock inhibit input should only be done when the clock input is

high. A buffered direct clear input overrides all other inputs, including

the clock, and sets all flip-flops to zero.
