What are the key features of CD74AC05EE4?
- 6-channel inverting open-drain outputs sinking up to 24 mA for LED driving and wired-OR bus applications
- AC CMOS logic family delivering high-speed switching with 50 pF load capacitance in a through-hole 14-pin PDIP
- REACH-compliant e4 solder coding enabling drop-in use in RoHS-regulated industrial and consumer designs
What is CD74AC05EE4 used for?
The CD74AC05EE4 is used in logic-level translation, wired-OR bus arbitration, and LED or relay driving circuits where 6 independent open-drain inverting channels are required from a single 14-pin through-hole package. Its AC CMOS technology provides fast propagation delays suitable for signal buffering in digital control boards and industrial interface cards. The open-drain outputs allow multiple devices to share a common output bus with a single pull-up resistor, simplifying multi-master communication designs.

Frequently Asked Questions
How much current can each open-drain output of the CD74AC05EE4 sink, and can it directly drive an LED?
Each open-drain output of the CD74AC05EE4 can sink up to 24 mA (IOL max), which is sufficient to directly drive standard 5V LEDs through a current-limiting resistor without needing an external transistor, making it practical for status indicator arrays in industrial panel designs.
How does the CD74AC05EE4 enable wired-OR bus arbitration in a multi-master digital system?
Because the CD74AC05EE4 has open-drain outputs, multiple channels or devices can drive a common bus line low independently while a single pull-up resistor holds the line high when all outputs are off, implementing wired-OR logic at signal frequencies supported by the AC family with a 50 pF load capacitance.
Which board prototyping scenarios favor the 14-pin PDIP package of the CD74AC05EE4 over an SOIC version?
The 14-pin PDIP package plugs directly into solderless breadboards and standard DIP IC sockets with 2.54mm pitch, making the CD74AC05EE4 a practical choice for rapid prototyping, laboratory evaluation, and educational lab kits where surface-mount soldering is not available.
Is the CD74AC05EE4 REACH-compliant, and does the e4 solder coding indicate lead-free construction?
Yes, the CD74AC05EE4 carries a REACH Compliant status and JESD-609 e4 coding, which confirms Pb-free (lead-free) solder construction meeting RoHS Directive requirements, allowing it to be used in consumer electronics and industrial equipment shipped to EU markets without restriction.
