Frequently Asked Questions
What is the SN74ACT564N and what are its key specifications?
The SN74ACT564N is an octal (8-bit) D-type edge-triggered flip-flop with inverted 3-state outputs from Texas Instruments. It operates on a 5V supply, features TTL-compatible inputs (ACT family), a propagation delay of approximately 25ns, and comes in a 20-pin PDIP through-hole package. It includes an active-low output enable (OE) pin and a clock (CLK) input for synchronous data latching.
What are the typical applications of the SN74ACT564N?
The SN74ACT564N is commonly used as a bus interface register, address latch, and data storage element in microprocessor systems. Its 3-state inverted outputs make it ideal for bidirectional bus designs, memory address buffers, I/O port expanders, and pipeline data registers in industrial control and embedded applications.
What is the difference between SN74ACT564N and SN74ACT574N?
Both are octal D-type flip-flops in the ACT logic family, but the SN74ACT564N has inverted (active-low) 3-state outputs, while the SN74ACT574N provides non-inverting outputs. Choose the SN74ACT564N when downstream logic requires active-low data, and the SN74ACT574N for direct (non-inverted) output applications.
What package does the SN74ACT564N come in?
The SN74ACT564N comes in a 20-pin PDIP (Plastic Dual In-line Package) through-hole package with 2.54mm pitch, making it suitable for breadboard prototyping, through-hole PCB assembly, and industrial designs where socket mounting is preferred.
