Features

The SN74LS164N is an 8-bit serial-in, parallel-out shift register, part of the Texas Instruments 74LS family. Key features include:
1. Data Input: Serial data is input through the DS pin, allowing for the sequential loading of data bits.
2. Parallel Output: Outputs Q0 to Q7 provide simultaneous access to the stored data.
3. Clock Control: Data is shifted on the rising edge of the clock signal (CP), enabling synchronous operation.
4. Asynchronous Reset: The reset pin (RST) allows for immediate clearing of all outputs to a low state.
5. High-Speed Operation: Designed for operation at up to 25 MHz, suitable for high-speed applications.
6. Low Power: Consumes low power due to the LS (Low Power Schottky) technology.
7. TTL Compatible: Compatible with TTL logic levels, making it easy to interface with other TTL devices.
8. Wide Supply Voltage Range: Operates from a 4.75V to 5.25V supply, making it versatile for various applications.
