Frequently Asked Questions
What is the maximum operating frequency of CD74ACT74E and how much output current can it sink?
CD74ACT74E operates at up to 85 MHz maximum frequency and sinks up to 24 mA output current, making it capable of driving capacitive bus loads of 50 pF in high-speed synchronous digital logic and frequency divider applications.
How does CD74ACT74E handle TTL-to-CMOS logic level interfacing in a 5 V system?
CD74ACT74E's ACT-series logic features TTL-compatible input thresholds while providing CMOS output voltage levels, allowing it to directly interface 5 V TTL signal sources to CMOS logic systems without level-shifting at clock speeds up to 85 MHz.
When is a DIP-14 package like CD74ACT74E preferred over an SOIC version for a flip-flop design?
DIP-14 packaging in CD74ACT74E is preferred in prototyping, education, and low-volume through-hole PCB production where breadboard insertion and hand soldering are required. The 0.1-inch pitch accommodates standard through-hole footprints without SMD assembly equipment.
Can CD74ACT74E replace 74ACT74 devices from other manufacturers in existing PCB designs?
CD74ACT74E is functionally and pin-compatible with industry-standard 74ACT74 dual D flip-flops from other manufacturers. Its 85 MHz speed, 24 mA sink current, and 14-pin DIP footprint match the standard specification, enabling direct drop-in replacement without schematic or layout changes.
