Product details

Each of the four independent gates performs the Boolean OR function on two inputs, making this a standard building block for glue logic, combinatorial signal routing, and control-path gating in digital systems. The 74AC series delivers higher speed and lower power than the original 74HC family while maintaining CMOS-level noise margins. This part is housed in a 14-pin plastic DIP (0.300" body width) for through-hole assembly, which suits prototyping, legacy board rework, and designs where vibration resistance or manual soldering is preferred over surface-mount. Typical applications include address decoding, clock gating, signal multiplexing, and general-purpose logic consolidation in PLC I/O modules, motor drive control boards, and instrumentation backplanes.

Pricing and availability are confirmed at quote time through independent distribution channels — no allocation pressure on this mature logic family.

Frequently asked questions

What is the difference between SN74AC32N and SN74HC32N?

Both are quad 2-input OR gates in 14-DIP. The 74AC series offers faster propagation delay (7.5ns vs approximately 10-15ns for HC at 5V) and higher output drive (24mA vs approximately 4mA for HC). The 74AC also has tighter input threshold specifications. For a direct replacement in an existing HC socket, verify the input logic levels match your driving stage — AC thresholds are lower than HC, which can improve noise margin on 3.3V systems but may cause false triggering if the upstream driver has weak high-level output.

Is SN74AC32N pin compatible with 74LS32?

Yes, the SN74AC32N is pin-compatible with the 74LS32 in the same 14-DIP footprint. Both are quad 2-input OR gates with the same pinout (GND pin 7, VCC pin 14). The AC version operates at lower power and wider supply range than the bipolar LS family.
