Nexperia Surface Mount 8-Bit Serial-in/Parallel-out Shift Register 16-Pin 2-6V 125°C 74HC595BZX

Nexperia 74HC595BZX is an advanced 8-bit serial-in/parallel-out surface mount shift register in a 16-pin compact package. This device supports separate clocks for both the shift register and the storage register, providing precise data transfer control essential for digital circuits requiring timing accuracy. It operates within a wide supply voltage range from 2.0 volts to 6.0 volts, allowing versatile integration into various electronic systems.

The shift register features serial input (DS) and serial output (Q7S) pins that enable cascading multiple ICs for extended bit sequences. An asynchronous reset input (MR) clears all bits in the shift register when driven LOW, providing a reliable initialization method. Data shifting is controlled on the LOW-to-HIGH clock transitions at the SHCP input, while the storage register captures data on similar transitions via the STCP clock input. This allows the shift register to remain one clock pulse ahead when both clocks are tied together, optimizing data timing.

Outputs of the storage register are equipped with 3-state logic controlled by the output enable pin (OE). When OE is HIGH, outputs transition to a high-impedance state, allowing bus sharing and multiplexing arrangements. The device’s low power CMOS design ensures minimal power dissipation alongside high noise immunity, making it ideal for industrial and commercial electronics, including counters, data storage, and control applications.

The 74HC595 series by Nexperia is designed to withstand temperatures up to 125° Celsius, suitable for demanding thermal environments. The package dimensions are 4.9 mm length, 4.3 mm width, and 1.1 mm height, optimized for surface mount technology on printed circuit boards.
