NXP 74HC4094D,653 8-stage Shift-and-Store Bus Register

The NXP 74HC4094D,653 is a high-performance, 8-stage serial shift register that provides an essential function in digital electronics. This integrated circuit (IC) is part of the 74HC family, which is well-known for its high-speed CMOS technology. The device is designed to operate with a 2 V to 6 V power supply, making it suitable for a wide range of applications in both commercial and industrial environments.

The 74HC4094D,653 features an 8-bit serial-in/parallel-out shift register with a storage register and 3-state outputs. Data is shifted on the positive-going transitions of the shift register clock input (CP) and the data in the storage register is transferred to the output buffer on a positive-going transition of the storage register clock input (STR). This mechanism allows for the serial input to be converted into a parallel output, making the device ideal for expanding the width of IO ports in microcontroller applications.

One of the key attributes of this product is its versatility. It can be used for driving LEDs, reading a chain of switches, or for general purpose serial-to-parallel data conversion. The 3-state output stage is designed to drive highly capacitive or relatively low-impedance loads, which is essential for interfacing with modern microcontrollers and other digital logic circuits.

The IC comes in a slim SO16 package, which is beneficial for space-constrained applications. The 74HC4094D,653 is specified over a -40°C to +125°C temperature range, ensuring reliable operation under extreme conditions. Additionally, it is compatible with TTL levels, which allows for easy integration into existing systems without the need for level shifting.

In summary, the NXP 74HC4094D,653 is a robust and versatile component that is perfect for applications requiring serial-to-parallel data conversion with additional storage capability. Its high-speed operation, wide operating voltage range, and 3-state outputs make it a valuable addition to any digital electronics toolkit.
