What this OR gate brings to a 5V board
The SN74ACT32N is a Texas Instruments quad 2-input OR gate from the 74ACT family — a 5V CMOS logic series that matches the speed of advanced TTL while keeping the low static power of CMOS. Four independent OR gates share a common 4.5V to 5.5V supply rail, each capable of sourcing or sinking 24 mA at the output. Propagation delay sits at 9 ns typical into a 50 pF load at 5V, fast enough for most through-hole glue logic but not a candidate for high-speed synchronous buses. Quiescent current is a mere 2 µA, so it won't load down a battery-backed rail or a lightly loaded power supply. The 14-pin DIP package (0.300" body) is breadboard-friendly and hand-solderable — a natural fit for prototyping, rework, or low-volume production where a socket makes field swaps easy. The industrial temperature range (-40°C to 85°C) covers factory-floor controllers, outdoor telecom enclosures, and HVAC panels; it is not rated for under-hood automotive but is fine for most industrial and commercial environments.
Lifecycle and compliance
The SN74ACT32N is listed as Active in production — no end-of-life notice, no last-time-buy pressure. It is RoHS3 compliant, so it meets the current EU restriction directive without exemption issues. The 74ACT series is a mature logic family; TI continues to support it for industrial and legacy designs that need a through-hole OR gate.
