Working Principles

The 74HC165BQ-Q100,115 is a serial-in, parallel-out shift register. It stores and transfers data in an 8-bit format. The serial data input (SER) receives the data bit by bit, which is then shifted into the register using the clock input (CLK). The shift/load input (SH/LD) controls whether the data is shifted or loaded into the register. When SH/LD is low, the data is shifted, and when it is high, the data is loaded in parallel. The output enable input (OE) enables or disables the outputs. The QH' pin provides the serial output, while the QH pins provide the parallel outputs.

Detailed Application Field Plans

• Industrial automation: Used for data storage and transfer in control systems.
• Communication devices: Enables serial-to-parallel conversion in data communication circuits.
• Test and measurement equipment: Facilitates data acquisition and analysis.
• Automotive electronics: Used in various applications such as dashboard displays and sensor interfaces.

Detailed and Complete Alternative Models

• SN74HC165N: DIP package, similar specifications and features.
• CD74HC165E: PDIP package, compatible functionality with minor variations.
• MC74HC165AN: DIP package, comparable performance and characteristics.

Note: These alternative models may have slight differences in package type, pin configuration, or operating temperature range, but they serve similar purposes and can be used as substitutes based on specific requirements.
