What is 74164 IC?
74LS164 is a high speed shift register with serial input of data and parallel output of data. It is an 8-bit IC. Data at serial input is fed through 1 input AND gate and it is synchronous with LOW to HIGH transition of the clock. In other words, the transition of data occurs on every positive edge of the input clock.
Which IC is used for shift register?
Commonly available IC’s include the 74HC595 8-bit Serial-in to Serial-out Shift Register all with 3-state outputs.
How many pins are require to give any type of input in 74ls164?
The SN74LS164 is a 14 pin IC, it has 4 input pins, 8 output pins, power, and ground. SN74LS164 needs 4 lines of a microcontroller. One for the Clock, one for Clear, and two input pins (A & B). Input Pins A and B work as a logical AND gate, meaning if both pins are logic high (5 volts) then it will read 1.
What is universal register?
A Universal shift register is a register which has both the right shift and left shift with parallel load capabilities. Universal shift registers are used as memory elements in computers. A Unidirectional shift register is capable of shifting in only one direction.
How does SISO shift register work?
SISO Shift Register SISO is one of the most basic forms of the shift registers. The data is loaded serially and retrieved serially. The output of the first DFF is fed into the input of the next DFF at each clock cycle, eventually reaching the last DFF / Output. This Shift register output is delayed from the input.
