What is 74HC164?


This is 8-Bit Serial-in/Parallel-out Shift Register.

In computing, a register is a small amount of fast storage within a CPU (central processing unit) that holds temporary data during processing. Registers are located on the CPU chip and are the fastest form of memory available to the processor

MM74HC164 8 Bit Serial in Parallel out Shift Register September 1983 Revised February 1999 MM74HC164 8 Bit Serial in Parallel out Shift Register General Description The MM74HC164 utilizes advanced silicon gate CMOS technology It has the high noise immunity and low consumption of standard CMOS integrated circuits It also offers speeds comparable to low power Schottky devices This 8 Bit shift register has gated serial inputs and CLEAR Each register bit is a D type master slave flip flop Inputs A B permit complete control over the incoming data A LOW at either or both inputs inhibits entry of new data and resets the first flip flop to the low level at the next clock pulse A high level on one input enables the other input which will then determine the state of the first flip flop Data at the serial inputs may be changed while the clock is HIGH or LOW but only information meeting the setup and hold time requirements will be entered Data is serially shifted in and out of the 8 Bit register during the positive going transition of the clock pulse Clear is independent of the clock and accomplished by a low level at the CLEAR input The 74HC logic family is functionally as well as pin out compatible with the standard 74LS logic family All inputs are prot

[ Detailed Data ]


There are several types of registers in a CPU, including: General-purpose registers: These registers can be used for storing any type of data and are often used for arithmetic operations. Control registers: These registers control various aspects of the CPU operation, such as interrupt handling and memory management. Status registers: These registers hold information about the status of the CPU, such as whether a particular instruction has been executed.
