SN74HC32N Quad 2-Input OR Gate Logic IC — DIP-14, 2–6V, 7ns, ±25mA (5-Pack)

SN74HC32N Quad 2-Input OR Gate Logic IC — DIP-14, 2–6V (5-Pack)

The SN74HC32N contains four independent 2-input OR gates in a DIP-14 through-hole package — each gate outputs HIGH when either or both inputs are HIGH. Part of the 74HC high-speed CMOS logic family, operating from 2V to 6V with 7ns propagation delay and ±25mA output drive current. Pin-compatible with 74LS32, MC74HC32AN, and HEF4075. Pack of 5 (20 OR gate channels total).

OR Gate Truth Table

• A=0, B=0 → Y=0
• A=0, B=1 → Y=1
• A=1, B=0 → Y=1
• A=1, B=1 → Y=1 (output HIGH if any input HIGH)

74HC32 vs 74LS32 vs 74HCT32

• 74HC32 (this IC): CMOS, 2–6V, low power, high speed — for 3.3V and 5V digital logic
• 74LS32: TTL, 5V only, higher power — legacy TTL circuits
• 74HCT32: CMOS with TTL-compatible inputs — for interfacing TTL outputs to CMOS

Typical Applications

• Logic signal combining (OR function)
• Interrupt signal merging (multiple sources to one MCU pin)
• Enable signal generation
• Digital logic circuit design and education
• Combinational logic prototyping

SN74HC32N quad OR gate, 5-pack — DIP-14, 2–6V, 7ns, ±25mA for digital logic circuit design, signal combining, and electronics prototyping.
