Frequently Asked Questions

What is the output enable polarity of the CD74AC240EE4?

The CD74AC240EE4 uses an active-low enable control signal. When the enable pin is driven low, the 3-state outputs are active; when it is high, the outputs enter a high-impedance state, allowing multiple drivers to share the same bus without conflict.

What package does the CD74AC240EE4 come in?

The CD74AC240EE4 is packaged in a 20-pin through-hole dual-in-line package (PDIP), conforming to JESD-30 code R-PDIP-T20. This package is suitable for breadboard prototyping and through-hole PCB assembly applications.

Is the CD74AC240EE4 RoHS compliant?

Yes, the CD74AC240EE4 carries a JESD-609 e4 code, indicating it is lead-free and fully RoHS compliant. The Pbfree Code is listed as Yes, making it suitable for use in environmentally compliant end products shipped globally.

What logic family does the CD74AC240EE4 belong to?

The CD74AC240EE4 belongs to the AC (Advanced CMOS) logic family, which provides high-speed switching performance comparable to TTL while maintaining CMOS low-power characteristics. It supports a 50pF load capacitance and unidirectional data flow.
