74HCT574D Flip Flops by Nexperia Semiconductor (NXP) (Obsolete Lifecycle)

Description

The Nexperia 74HCT574D is a high-speed CMOS octal D-type flip-flop with three-state outputs. It features eight independent D-type flip-flops, each with individual clock, set, and reset inputs. The device operates at a supply voltage of 4.5 to 5.5V and has a temperature range of -40°C to +80°C. The 74HCT574D is designed for use in digital systems requiring high-speed data transfer and storage. Its three-state outputs allow for easy connection to other logic devices or memory elements. The device's CMOS technology ensures low power consumption, making it suitable for battery-powered or energy-efficient applications. In summary, the Nexperia 74HCT574D is a high-speed octal D-type flip-flop with three-state outputs, designed for use in digital systems requiring fast data transfer and storage.

Package

The package type of 74HCT574D is SOT-163 (SMD, SOL20).

Pinout

The 74HCT574D is an 8-bit serial-in/serial-out shift register with a D-type flip-flop at each stage. It has a pin count of 20.

Here's a concise breakdown of the pins:

• Clock input (CK): Clocks the data into the flip-flops.
• Serial input (DS): Serial input to the shift register.
• Master reset (MR): Resets all flip-flops to logic zero state.
• Output enable (OE): Enables or disables the outputs.
• Data output (Q0-Q7): The 8-bit serial output.

The device is designed for use in digital systems requiring a high degree of noise immunity and a low power consumption.
