M74HC164 8 BIT SIPO SHIFT REGISTER

s The M74HC164 is an high speed CMOS 8 BIT b SIPO SHIFT REGISTER fabricated with silicon O gate C2MOS technology. - The M74HC164 is an 8 bit shift register with serial t(s) data entry and an output from each of the eight stages. Data is entered serially through one of two c inputs (A or B), either of these inputs can be used u as an active high enable for da.

Features

74HC164RM13TR M74HC164TTR transition on the clock inputs shifts data one place to the right and enters into QA the logic NAND of the two data inputs (A x B), the data that existed before the rising clock edge. A low level on the clear input overrides all other inputs and clears the register asynchronously, forcing all Q outputs low. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
