74HC165N – TBC

Overview

The 74HC165N, an 8-bit shift register, excels at parallel-to-serial data conversion, a fundamental task in many digital systems. Its core strength lies in its ability to asynchronously load 8 bits of parallel data and then synchronously shift it out serially, driven by a clock signal. A critical design consideration when utilizing the 74HC165N is managing the trade-off between parallel load speed and serial shift clock frequency; while parallel loading is asynchronous, the serial output rate is directly limited by the maximum clock frequency, necessitating careful timing analysis to avoid data corruption in high-speed applications.

Key Features

• 8-bit asynchronous parallel load
• Synchronous serial data input (DS)
• Complementary serial outputs (Q7 and Q7)
• Gated OR clock input with optional clock enable (CE)
• High-speed Si-gate CMOS technology
• DIP-16 package (approx. 19.3mm x 6.35mm x 3.3mm)
