What this 8-input NAND gate does for a 5V logic bus
The Texas Instruments 74ACT11030N is a single 8-input NAND gate in a through-hole 14-DIP package, part of the 74ACT family. The key timing spec is 8.1 ns maximum propagation delay at 5V with a 50 pF load, which gives you clean margin in a 5V address decoding or interrupt-combining path. Quiescent current sits at 4 µA max, so it won't load down a mixed-signal board's 5V rail.
Supply voltage and input thresholds — fit for 5V TTL/CMOS mixed systems
The 4.5V to 5.5V supply range matches a regulated 5V rail with ±10% tolerance. Input logic low is 0.8V max and high is 2V min, which means this gate accepts standard 5V TTL levels directly and also works with 3.3V CMOS outputs that swing above 2V. The 24 mA symmetric output drive can sink or source enough current to drive a 5V relay coil through a transistor or feed a bus transceiver without extra buffering.
Package and mounting — through-hole for prototyping and legacy boards
The 14-DIP (0.300", 7.62mm) body with through-hole mounting and a 14-PDIP supplier package is the standard footprint for breadboard prototyping, socketed production, or rework on legacy PCB assemblies that avoid SMT. No special reflow profile needed — hand-solder or wave-solder as usual for DIP packages.
For a BOM line using this part, you are not facing a forced redesign or a sourcing scramble in the near term.
