HD74LS166A 8-bit Shift Register REJ03D0450-0400 Rev.4.00 May 10, 2006 The inputs are buffered to lower the drive requirements to one series 74 or 74LS standard load, respectively. Input clamping diodes minimize switching transients and simplify system design. This parallel in or serial-in, serial-out shift register has a plexity of 77 equivalent gates on a monolithic chip. This device Features gated clock inputs and an overriding clear input. The parallel-in or serial-in modes are established by the shift / load input. When high, this input enables the serial data input and couples the eight flip-flops for serial shifting with each clock pulse. When low, the parallel (broadside)...
