SN74HCS165BQBR - Texas Instruments 8-Bit Parallel-Load Shift Registers

The SN74HCS165BQBR from Texas Instruments is a high-performance, 8-bit shift register designed for use in digital systems. It is a part of the 74HCS logic family, which is characterized by its high speed and low power consumption, making it an ideal choice for a wide range of applications in modern electronics.

This integrated circuit features an 8-bit serial or parallel-input, serial-output shift register that allows for the conversion of parallel data into serial data, which can then be transmitted over a single line, reducing the number of required interconnections. This functionality is particularly useful in applications where data needs to be transferred over long distances or through limited I/O ports.

The SN74HCS165BQBR operates with a 2-V to 6-V V<sub>CC supply, providing a flexible power range that accommodates various logic levels and is compatible with most microcontrollers and digital systems. This shift register has a wide operating temperature range from -40°C to 85°C, ensuring reliable performance in diverse environmental conditions.

Key features of the SN74HCS165BQBR include:

• 8-bit parallel or serial input
• Serial output capability
• Shift/preset capability synchronous with the system clock
• Direct overriding clear function
• Complementary outputs
• Wide operating voltage range of 2 V to 6 V
• Low power consumption
• High-impedance state during power up and power down
• Available in a small-outline package

The device is provided in a compact 16-pin SSOP (Shrink Small-Outline Package) that is suitable for space-constrained applications. The SN74HCS165BQBR also supports the bus-hold feature, which retains the last valid input state when no input is present, thereby reducing the need for external pull-up or pull-down resistors.

With its robust design and high functionality, the SN74HCS165BQBR is an excellent choice for applications such as data acquisition systems, microprocessor interfaces, and digital signal processing, where reliable data shifting is required. Texas Instruments' commitment to quality ensures that this shift register will provide a dependable solution for your digital logic needs.
