Product Overview: SN74LV165ANSR by Texas Instruments

The SN74LV165ANSR from Texas Instruments is a high-performance, 8-bit parallel-load shift register that is designed for use in a wide range of digital applications. This integrated circuit is part of the LV family, signifying its low-voltage operation, and it is particularly well-suited for systems that require low power consumption without sacrificing speed and performance.

The device features a 2-V to 5.5-V V<sub>CC operation, making it versatile for interfacing with both 3.3V and 5V logic levels. This flexibility allows the SN74LV165ANSR to be integrated into various digital systems, from microcontrollers to digital signal processors, without the need for level shifting.

With its direct overriding clear (SRCLR) input and clock (CLK) input, the SN74LV165ANSR provides a straightforward mechanism for data manipulation. The parallel data is loaded into the register using the parallel input lines (A to H), and upon a positive transition of the clock, the data is serially shifted out at the QH' output. This serial output can be used in a daisy-chain configuration for cascading multiple shift registers, expanding the input capability without increasing the number of input lines.

The SN74LV165ANSR is available in a compact 16-pin SOP (Small Outline Package), which is conducive to space-saving requirements on printed circuit boards. The device also features a wide operating temperature range of -40°C to 85°C, ensuring reliability in various environmental conditions.

Key features of the SN74LV165ANSR include:

• 8-bit serial or parallel input/output
• 2-V to 5.5-V V<sub>CC operation
• Direct overriding clear
• Shift register function with serial output
• Compatible with 3.3V and 5V logic levels
• 16-pin SOP packaging for space efficiency
• Wide operating temperature range

In summary, the SN74LV165ANSR is a versatile and efficient component for digital systems requiring a reliable shift register. Its low-voltage operation and compatibility with various logic levels make it an ideal choice for modern electronic applications.
