Description

The SN74LS164N is an 8-bit serial-in, parallel-out shift register from Texas Instruments, commonly used in digital circuits for data storage and transfer. It features a low-power Schottky design, which helps in reducing power consumption and improving speed. The SN74LS164N operates with two input pins (A and B) for serial data input, which are usually tied together for single data input. The device also includes eight parallel output pins (Q0 to Q7), allowing the stored data to be accessed simultaneously.
The shift register is clocked using a clock input pin (CP), and the data is shifted on the positive edge of the clock signal. An asynchronous clear input (CLR) is provided to reset all outputs to low, ensuring that the register can be quickly initialized. The SN74LS164N is packaged in a standard Dual In-line Package (DIP), making it easy to integrate into various projects. It is widely used in applications like digital counters, LED displays, and data conversion systems due to its reliability and ease of use.
