The SN74ACT564NSR from Texas Instruments is a high-performance, octal edge-triggered D-type flip-flop integrated circuit. This device is designed for use in a wide array of applications ranging from data storage, data transfer, to system resource management in complex digital systems. It is particularly well-suited for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

The SN74ACT564NSR features eight D-type flip-flops with a common clock (CP) and output enable (OE) inputs. Each flip-flop is edge-triggered, capturing data on the rising edge of the clock signal, and can be reset by an asynchronous clear input. This allows for precise control and timing of data flow within digital circuits, ensuring reliable and predictable operation.

The device operates over a wide voltage range from 4.5 V to 5.5 V and is characterized for operation from -40°C to 85°C, making it versatile for various environmental conditions. Its low power consumption and high noise immunity are achieved through Texas Instruments' advanced CMOS technology. Additionally, the SN74ACT564NSR comes in a 20-pin SOP (Small Outline Package), which is suitable for space-constrained applications.

Key features of the SN74ACT564NSR include:

• Eight edge-triggered D-type flip-flops with clear
• Wide operating voltage range of 4.5 V to 5.5 V
• Outputs can drive up to 15 LSTTL loads
• Low power consumption
• High noise immunity characteristic of CMOS devices
• ±24-mA output drive at 5 V
• Direct bus connection when high output enable (OE) is inactive
• Industrial temperature range: -40°C to 85°C

With its robust design and high functionality, the SN74ACT564NSR is an ideal choice for designers looking for a reliable flip-flop IC to implement in their digital systems. Its ease of integration and support for high-speed data operations make it a go-to component for a variety of electronic applications.
