The SN74LV165APWT is a high-performance, 8-bit parallel-load shift register designed and manufactured by Texas Instruments. This integrated circuit is part of the 74LV family, which operates at a lower voltage range for optimal power efficiency. The SN74LV165APWT is ideal for applications in data acquisition systems, microprocessor interface, and digital signal processing where space constraints and low power consumption are critical factors.

Key Features

• Logic Family: The device belongs to the LV family, indicating low-voltage operation which is suitable for battery-powered and portable applications.
• Operating Voltage: The SN74LV165APWT operates within a voltage range of 2V to 5.5V, ensuring compatibility with both 3.3V and 5V logic levels.
• Parallel or Serial Output: This shift register can output data in either a parallel format, which is useful for interfacing with data buses, or serially for cascading multiple devices or reducing the number of I/O pins used.
• Shift/Register Clock Input: The device features separate clock inputs for shift and register operations, providing flexibility in timing and control.
• Direct Clear Function: An asynchronous clear function allows for the immediate clearing of the shift register, enhancing the control over data manipulation.
