What this AND gate brings to your board
The CD74ACT08E is a Texas Instruments 74ACT-series quad 2-input AND gate in a through-hole 14-DIP package. It runs on a 4.5V to 5.5V supply and delivers 24mA of drive current per output.
Military temp range — not just a number
Rated -55°C to 125°C operating temperature, so this part is at home in avionics bay electronics, satellite bus interfaces, downhole instrumentation, and any environment where the enclosure sees freeze-thaw or sits next to a hot power stage. The 4 µA quiescent current max is negligible in those systems.
Through-hole DIP: field-swappable, socket-ready
The 14-pin DIP package (0.300" body width) drops into a socket or solders into plated through-holes with a standard iron.
Logic thresholds and supply compatibility
Input logic levels are 0.8V low and 2V high over the full supply range. That means it is a 5V-only part — do not try to run it at 3.3V because the 2V high threshold leaves almost no noise margin below a 3.3V rail. For a 3.3V system, look at the 74LVC08 family instead (SN74LVC08ADR is a surface-mount option). The pinout matches the classic 74LS08, so it is a drop-in replacement on existing boards that were laid out for the LS family.
Active lifecycle, no LTB worry
Texas Instruments lists the CD74ACT08E as Active and RoHS3 compliant. No last-time-buy notice, no end-of-life clock ticking. For a production BOM that needs a through-hole AND gate, this part is not going away soon.
