8-BIT PARALLEL-LOAD SHIFT REGISTERS

The 'LV166A devices are 8-bit parallel-load shift registers, designed for 2-V to 5.5-V VCC operation. 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 loadin...
