description/ordering information (continued)

The ’LV166A parallel-in or serial-in, serial-out registers feature gated clock (CLK, CLK INH) inputs and an

overriding clear (CLR) input. The parallel-in or serial-in modes are established by the shift/load (SH/LD) input.

When high, SH/LD enables the serial (SER) data input and couples the eight flip-flops for serial shifting with each

clock (CLK) pulse. When low, the parallel (broadside) data inputs are enabled, and synchronous loading occurs

on the next clock pulse. During parallel loading, serial data ow is inhibited. Clocking is accomplished on the

low-to-high-level edge of CLK through a 2-input positive-NOR gate, permitting one input to be used as a

clock-enable or clock-inhibit function. Holding either CLK or CLK INH high inhibits clocking; holding either low

enables the other clock input. This allows the system clock to be free running, and the register can be stopped

on command with the other clock input. CLK INH should be changed to the high level only when CLK is high.

CLR overrides all other inputs, including CLK, and resets all flip-flops to zero.

These devices are fully specied for partial-power-down applications using Ioff. The Ioff circuitry disables the

outputs, preventing damaging current backflow through the devices when they are powered down.
