Product Overview: 74HC595BQ from NXP

The 74HC595BQ is a high-quality 8-bit serial-in, parallel-out shift register, which is part of the 74HC family, produced by NXP Semiconductors. This integrated circuit (IC) is designed to have a broad range of applications, including in the automotive industry, consumer electronics, and industrial automation systems. Its primary function is to receive data serially and output it in a parallel format, allowing for an expansion of output ports while minimizing the number of required I/O pins on a microcontroller or other controlling devices.

The 74HC595BQ is equipped with an 8-bit serial shift register and an 8-bit D-type storage register. The data is shifted on the positive-going transitions of the shift register clock input (SHCP). Once the data is in the shift register, it can be transferred to the storage register or be output to the Q′S serial output on positive-going transitions of the storage register clock input (STCP). The output enable input (OE) allows the user to place the eight outputs in either a high-impedance OFF-state or an active state, thus providing control over the output pins.

This device operates on a wide supply voltage range from 2.0V to 6.0V and features a high noise immunity characteristic of CMOS devices. The 74HC595BQ is also characterized by its low power consumption, making it suitable for battery-operated applications. Additionally, the IC supports a high-speed clock, with shifting frequencies of up to 100 MHz at 2.0V, which makes it an excellent choice for high-speed data processing tasks.

The 74HC595BQ comes in a DHVQFN16 package, which is a leadless, extremely thin quad flat package with no leads and a 16-pin configuration. This compact package is ideal for space-constrained applications and provides good thermal performance.

In summary, the NXP 74HC595BQ shift register is a versatile and reliable component that can significantly expand the digital output capabilities of your electronic designs, while maintaining a small footprint and efficient power consumption.
