Frequently Asked Questions
What is the maximum operating frequency of the CD74ACT574EE4?
The CD74ACT574EE4 operates at a maximum frequency of 110 MHz at nominal supply voltage in the ACT logic family. It also supports a 50 pF load capacitance, making it one of the faster options for octal flip-flop bus driver applications in high-speed digital systems.
What makes the CD74ACT574EE4 different from a standard 374-type flip-flop?
The CD74ACT574EE4 is described as the broadside version of the 374, meaning its input and output pins are arranged on opposite sides of the package for improved PCB routing. This pinout difference simplifies bus connections in board layouts while maintaining identical 8-bit D-type flip-flop with three-state output functionality.
What package does the CD74ACT574EE4 use?
The CD74ACT574EE4 comes in a 20-pin Dual In-line Package (DIP), with JESD-30 code R-PDIP-T20. This through-hole package is suitable for prototyping, breadboarding, and legacy PCB designs requiring socketed or hand-soldered components.
Is the CD74ACT574EE4 RoHS compliant?
Yes, the CD74ACT574EE4 carries a JESD-609 code of e4, confirming it is RoHS compliant and manufactured without hazardous substances such as lead. It is appropriate for use in environmentally regulated markets and lead-free assembly processes.
What are typical alternatives to the CD74ACT574EE4?
Functional alternatives include the SN74ACT574 from Texas Instruments in SOIC or TSSOP packages, as well as 74HCT574 series parts from other manufacturers for lower-speed applications. When substituting, verify the package footprint, operating voltage range, and propagation delay specifications to ensure compatibility.
