The NXP 74HCT165 is a high-speed Si-gate CMOS device that is pin compatible with Low-power Schottky TTL (LSTTL). It is designed to have the same high speed performance of LSTTL combined with the true CMOS low power consumption. This integrated circuit is an 8-bit parallel-load or serial-in shift registers with complementary outputs available from the last stage.

Key Features

• Logic Family: HCT
• Operation Mode: 8-bit Shift Right
• Number of Circuits: Single
• Output Type: Complementary
• Supply Voltage Range: 4.5V to 5.5V
• Pin Count: 16
• Operating Temperature Range: -40°C to +125°C
• Package Type: Available in various packages including SO, TSSOP, and DIP

Product Advantages

The 74HCT165 is particularly useful in applications where a series of data needs to be collected from sensors or buttons and then transmitted serially to a microcontroller or processor. Its parallel-load capability allows for faster data collection compared to serial-load shift registers. The device features a Master Reset (MR) input that clears the register, setting all outputs low. It also has a Clock Input (CP) that controls the state changes of the flip-flops on the rising edge of the clock pulse.

Applications

The 74HCT165 is versatile and can be used in a variety of digital applications. Common use cases include:

• Serial-to-parallel data conversion
• Remote data acquisition systems
• Data multiplexing
• Instrumentation and control systems
• Signal processing
• Industrial automation

With its robust design and the ability to operate across a wide temperature range, the NXP 74HCT165 is a reliable choice for designers looking to implement an 8-bit shift register in their digital logic applications.
