TC74HC166AP Overview
It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. It consists of parallel-in or serial-in, serial-out 8-bit shift register with a gated clock input and an overriding clear input. The parallel-in or serial-in modes are controlled by the SHIFT/ LOAD input.
TC74HC166AP Key Features
