Technical Details & Description

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 74ACT series is a mature logic family; TI continues to support it for industrial and legacy designs that need a through-hole OR gate.

Frequently asked questions

Is SN74ACT32N equivalent to SN74HC32N?

Both are quad 2-input OR gates in a 14-pin DIP, but the SN74ACT32N uses the ACT logic family (advanced CMOS with TTL-compatible inputs) while the SN74HC32N uses the HC family (CMOS-level inputs). The ACT version has tighter propagation delay (9 ns vs roughly 15 ns for HC at 5V) and can be driven directly by TTL outputs without a pull-up. Pinout is identical, so they are socket-compatible, but the input thresholds differ.

What is the power consumption of SN74ACT32N?

Quiescent supply current is 2 µA maximum. Dynamic power scales with frequency and load; at a few MHz into a light load the total draw stays well under 10 mA.

What is the propagation delay of SN74ACT32N?

Maximum propagation delay is 9 ns at 5V supply with a 50 pF load. That is the spec for both high-to-low and low-to-high transitions.

Is SN74ACT32N RoHS compliant?

Yes, it is RoHS3 compliant (the current EU standard), with no exemptions listed.
