SN74HC165DBR

The SN74HC165DBR is a high-performance, 8-bit parallel-in/parallel-out (PISO) shift register manufactured by Texas Instruments. It is part of the 74HCxx series of logic devices, which are known for their high-speed performance and low power consumption.

Description:

The SN74HC165DBR is a shift register that can store and shift 8 bits of data in parallel. It has a serial input and a parallel output, allowing data to be shifted in one bit at a time and then output in parallel. The device also features a storage register that can hold the shifted data until it is ready to be output.

Features:

1. 8-bit parallel-in/parallel-out shift register
2. Serial input and parallel output
3. Storage register for data retention
4. 3-state outputs for applications with multiple devices
5. High-speed performance (typical propagation delay of 3.5 ns)
6. Low power consumption (typical supply current of 2.2 mA)
7. Wide operating voltage range (2.0V to 6.0V)
8. Available in a small-outline integrated circuit (SOIC) package

Applications:

The SN74HC165DBR is suitable for a variety of applications that require data storage and shifting, including:

1. Digital signal processing
2. Data acquisition systems
3. Communication interfaces
4. Microcontroller-based systems
5. Counters and frequency dividers
6. Memory address decoding
7. Parallel data transfer and synchronization
8. General-purpose data storage and manipulation

In summary, the SN74HC165DBR is a versatile and high-performance shift register that can be used in a wide range of applications requiring parallel data storage and shifting. Its small size, low power consumption, and high-speed performance make it an ideal choice for many digital systems.
