Product Overview: 74HC564D from NXP Semiconductors

The 74HC564D is a high-performance integrated circuit produced by NXP Semiconductors, a leader in the semiconductor industry. This chip belongs to the 74HC family, which is well-known for its high-speed CMOS technology. The 74HC564D is an octal D-type flip-flop with three-state inverting outputs, making it a versatile component for a wide range of digital applications.

The device features eight edge-triggered flip-flops with individual D-type inputs and three-state inverting outputs. The flip-flops are triggered on the falling edge of the clock pulse, and the inverting outputs ensure that the device can be used in bus-oriented systems by allowing multiple outputs to be connected together without causing contention.

Each flip-flop has a direct clear input, which enables synchronous reset, allowing the flip-flops to be cleared simultaneously when the clear input is taken low. This feature is critical for initializing or resetting digital circuits that require precise timing and control.

The 74HC564D operates with a wide supply voltage range of 2V to 6V, making it compatible with TTL levels and suitable for battery-operated devices, as well as industrial and automotive applications that require robust performance under varying voltage conditions.

The device is offered in a SO20 package, which is a small-outline package that is both space-saving and suitable for automated surface-mount assembly processes. This packaging, combined with the chip's low power consumption and high noise immunity, makes the 74HC564D an excellent choice for compact and efficient digital systems.

Key features of the 74HC564D include:

• Eight D-type flip-flops with three-state inverting outputs
• Edge-triggered on the falling edge of the clock pulse
• Direct clear input for synchronous reset
• Wide supply voltage range of 2V to 6V
• Compliance with JEDEC standard no. 7A
