The SN74HC164PW is a high-performance, 8-bit serial-in/parallel-out shift register produced by Texas Instruments. This integrated circuit is designed to be a versatile component for digital systems, offering a reliable means to convert serial data into parallel format, which is especially useful in expanding the number of outputs in microcontroller-based projects.
The device features two serial data inputs (A and B) that allow for cascading multiple devices without the need for external gates. Its clock input controls the sequential entry of the data into the register. The outputs are designed to drive up to 15 LSTTL loads, which makes the SN74HC164PW suitable for interfacing with a wide range of digital systems.
With an operating voltage range of 2V to 6V, the SN74HC164PW is compatible with standard TTL logic levels while also supporting the lower voltage requirements of some CMOS devices. This feature ensures that the IC can be integrated into both legacy systems and modern low-power designs.
The output of the SN74HC164PW is an 8-bit parallel word that can be used to drive LEDs, relays, or other digital circuits. With its direct overriding clear (Master Reset) input, the device can be quickly cleared to all zero output state, thus providing a convenient method of resetting the system during power-up or after an error condition.
Packaged in a TSSOP (Thin Shrink Small Outline Package), the SN74HC164PW is optimized for space-constrained applications. Its small form factor and low power consumption make it an excellent choice for portable and battery-powered devices. Moreover, the device's robustness is ensured by its balanced propagation delays and transition times, which provide reliable operation even in noisy environments.
Whether you're designing a microcontroller interface, a digital display system, or any application requiring serial-to-parallel conversion, the SN74HC164PW from Texas Instruments offers a high-quality, cost-effective solution that combines performance with flexibility.
