The CD74AC164E is a high-speed 8-bit serial-in/parallel-out shift register designed by Texas Instruments. This integrated circuit is part of the advanced high-speed CMOS family and comes in a 14-pin DIP (Dual In-line Package) enclosure, making it suitable for a wide range of applications in the digital domain. The device is specifically engineered to facilitate serial-to-parallel data conversion with high precision and reliability.

Featuring two serial data inputs (A and B) which allow for either single or dual input modes, the CD74AC164E is highly flexible in its operation. It includes eight parallel data outputs (Q0 to Q7) that change state on the rising edge of the clock input signal. This characteristic makes the CD74AC164E ideal for applications that require data to be shifted and stored efficiently, such as in digital signal processing, data display, and various automation systems.

The device operates over a wide voltage range from 3V to 5.5V, which provides a good margin for stability and ensures compatibility with TTL (Transistor-Transistor Logic) levels. Additionally, the CD74AC164E boasts a high noise immunity characteristic of CMOS devices, and it is capable of driving up to 10 LSTTL loads. These features contribute to the device's robust performance in electrically demanding environments and its ability to interface with various logic families.

Texas Instruments has designed the CD74AC164E with features such as 8-bit serial input to parallel output functionality, the ability to perform serial shifting with simultaneous parallel output, and edge-triggered clocking which all contribute to the device's utility in complex digital systems. The CD74AC164E is also characterized by the low power consumption typical of CMOS integrated circuits, making it a power-efficient choice for battery-operated devices.

In summary, the CD74AC164E from Texas Instruments is a versatile and reliable component for applications requiring efficient data conversion from serial to parallel form. Its compatibility with a wide range of operating voltages and other logic levels, along with its low power requirements and high noise immunity, make it an excellent choice for designers and engineers working on advanced digital systems.
