SN54/74LS166

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 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.
