NXP Semiconductors Shift Registers 74HC164DB,112

The 74HC164DB,112 is an 8-bit serial-in, parallel-out shift register designed for efficient data handling in digital circuits. It features two serial data inputs (DSA and DSB) and eight parallel outputs (Q0 to Q7), allowing for flexible data entry and output. The device operates on a supply voltage range of 2.0 to 6.0 V and is characterized by low power dissipation and high noise immunity, making it suitable for various applications. Data is shifted on the LOW-to-HIGH transitions of the clock input (CP), and an asynchronous master reset (MR) can clear the register outputs. The inputs are equipped with clamp diodes, enabling the use of current limiting resistors for interfacing with higher voltages than V_CC. The product complies with JEDEC standards and offers robust ESD protection, exceeding 2000 V for HBM and 200 V for MM. The 74HC164DB,112 is available in multiple package options, including SO14, TSSOP14, and DHVQFN14, and is specified for operation across a temperature range of -40 ¬8C to +125 ¬8C. This versatility and reliability make it a suitable choice for engineers looking to implement shift register functionality in their designs.
