SN74LS164NG4 - 8-Bit Parallel-Out Serial Shift Registers

The SN74LS164NG4 is a high-performance, 8-bit serial shift register that offers a practical solution for expanding the width of input/output ports in microcontroller-based systems. Manufactured by Texas Instruments, a leader in semiconductor solutions, this integrated circuit is designed for smooth serial-to-parallel data conversion.

The device features two serial data inputs (A and B) that allow the user to input data either independently or together for parallel loading. This versatility makes the SN74LS164NG4 suitable for a wide range of applications, including data multiplexing, signal processing, and digital system expansion.

With a direct overriding clear (CLR) input, the SN74LS164NG4 can be reset at any time, which is essential for ensuring data integrity and system reliability. The clear function is synchronous, allowing for precise control and timing of the reset operation.

The SN74LS164NG4 operates over a voltage range of 4.75 V to 5.25 V, making it compatible with standard TTL logic levels. This compatibility ensures that the device can be easily integrated into existing systems without the need for additional level-shifting components.

One of the key features of the SN74LS164NG4 is its edge-triggered clocking system, which ensures that all state changes occur on the rising edge of the clock pulse. This characteristic minimizes the risk of data corruption due to timing discrepancies and enables reliable operation in high-speed environments.

The output design of the SN74LS164NG4 allows for both serial and parallel outputs, enabling users to cascade multiple devices without the need for external circuitry. This cascading capability is particularly beneficial in applications requiring long sequences of shift registers or a large number of output lines.

Offered in a 14-pin DIP (Dual In-line Package), the SN74LS164NG4 is easy to handle and integrate into printed circuit boards (PCBs). Its industry-standard footprint ensures compatibility with a wide range of socket and soldering techniques, making it a versatile choice for both prototyping and production-scale applications.

In conclusion, the SN74LS164NG4 from Texas Instruments represents a robust and flexible solution for digital design engineers looking to expand the capabilities of their systems with a reliable and easy-to-use serial shift register.
