Product details

What the 24 mA output drive means for your bus

The CD74ACT244E is a 74ACT-series octal buffer with non-inverting, 3-state outputs in a 20-pin DIP package.

Through-hole DIP — still the right choice for retrofit and low-volume builds

The 20-DIP (0.300", 7.62 mm) through-hole package is a deliberate choice for breadboard prototyping, legacy board repair, or low-volume production where hand-assembly or wave-solder is the process. The 20-PDIP footprint is identical to the industry-standard 74ACT244 DIP layout, so it drops straight into existing sockets or plated through-holes without a board spin.

ROHS3 compliance is confirmed, so it passes the EU material restrictions without an exemption.

Frequently asked questions

What is the difference between 74ACT244 and 74HCT244?

The 74ACT244 uses advanced CMOS technology with a tighter input threshold (TTL-compatible) and typically higher output drive than the 74HCT244, which is a CMOS-input-level variant. Both are non-inverting octal buffers with 3-state outputs in the same 20-pin DIP footprint, but the ACT family is specified for faster edge rates and lower quiescent current at 5 V.

Is the CD74ACT244E RoHS compliant?

Yes, the CD74ACT244E is listed as ROHS3 compliant, covering the full RoHS substance restrictions without exemptions.
