NXP 74HC164DB 8-bit Serial-in/Parallel-out Shift Register

The NXP 74HC164DB is a high-speed Si-gate CMOS device and is part of the 74HC series. This integrated circuit is designed to provide a reliable and efficient solution for digital systems requiring serial-to-parallel data conversion. The 74HC164DB is an 8-bit, serial-in/parallel-out shift register that allows for the serial input of data and the parallel output of the same data, making it an essential component for expanding the number of input/output lines in microcontroller-based systems or for driving LEDs, displays, and other output devices.

Key Features

• Logic Family: The device belongs to the 74HC logic family, which is known for its high-speed operation and compatibility with TTL (Transistor-Transistor Logic) levels.
• Operating Voltage: It operates over a wide voltage range from 2.0V to 6.0V, catering to a variety of logic level requirements and ensuring compatibility with both low and high voltage systems.
• Shift Register: The 74HC164DB features an 8-bit serial-in/parallel-out shift register, which allows for the conversion of serial data input to parallel data output.
• Output Capability: This device can drive up to 15 LSTTL loads, providing sufficient current for many standard applications.
• Speed: The high-speed operation of the 74HC164DB is evidenced by its typical clock frequency of 24 MHz, making it suitable for high-speed data processing tasks.

Applications

The 74HC164DB is ideal for a broad range of applications, including:

• Serial-to-parallel data conversion
• Remote control holding registers
• LED and display drivers
• Interface circuitry for microprocessors
• Sequential timing applications

Package and Quality

The device is offered in a small 14-pin SSOP (Shrink Small Outline Package), which is suitable for space-constrained applications. The 74HC164DB is fully specified for partial Power-down applications using I<sub>OFF. The I<sub>OFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down. NXP's commitment to quality ensures that the 74HC164DB meets stringent industry standards for performance and reliability.
