SN74HC166A-Q1 - 8-BIT PARALLEL-LOAD SHIFT REGISTER

Description

ordering information This parallel-in or serial-in, serial-out register

Features

  • gated clock (CLK, CLK INH) inputs and an overriding clear (CLR) input. The parallel-in or C D CLK INH CLK GND 4 5 6 7 8 13 QH 12 G 11 F 10 E 9 CLR 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, ser.
