Frequently Asked Questions
What is the function of the SN74ACT563NSRE4?
The SN74ACT563NSRE4 is an octal D-type transparent latch that captures and holds 8 bits of data when the latch enable input is active. When the enable goes inactive, the outputs retain the last latched data state. Its active-low output enable allows the outputs to be tri-stated for bus sharing.
What are the key electrical specifications of the SN74ACT563NSRE4?
The SN74ACT563NSRE4 operates in the ACT logic family with a maximum output low current (IOL) of 24mA, a load capacitance of 50pF, and active-low control inputs. It is housed in a 20-pin SOIC package and is Pb-free with RoHS compliance, making it compatible with modern manufacturing requirements.
What package does the SN74ACT563NSRE4 use?
The SN74ACT563NSRE4 uses a 20-pin Small Outline Integrated Circuit (SOIC) package, identified by JESD-30 code R-PDSO-G20. This surface-mount package is compact and well-suited for high-density PCB designs, offering reliable soldering and good thermal performance in standard industrial assembly processes.
Is the SN74ACT563NSRE4 RoHS compliant?
Yes, the SN74ACT563NSRE4 is fully RoHS compliant and Pb-free, as indicated by its Pb-free code. The 'E4' suffix in the part number further confirms it meets the green and halogen-free requirements, making it suitable for environmentally regulated markets including the European Union and other regions with similar standards.
What is the difference between transparent and edge-triggered latches, and how does it apply to the SN74ACT563NSRE4?
A transparent latch passes data directly to the outputs when the latch enable is active (transparent mode), and latches the last data state when the enable goes inactive. The SN74ACT563NSRE4 operates in this transparent mode, unlike edge-triggered flip-flops which only capture data on a clock edge. This makes it ideal for address latching in multiplexed bus architectures.
