ON Semiconductor MC74HC02AN Quad 2-Input NOR Gate 14-Pin DIP Used Pull

Quad 2-Input NOR Gate in 14-Pin Plastic DIP - ON Semiconductor High-Speed CMOS Logic

Condition

Used pull, one piece in stock. The photographed chip is a black 14-pin plastic DIP marked with the ON Semiconductor logo, MC74HC02AN on the first line and CPCY0726G on the second. All fourteen leads are present, straight, in line, and bright with no solder residue, no bent or clipped pins, and no scorching or cracking on the body. Clean pins like these are normal on a socket-pulled part and are what the camera shows here. It arrived on pink anti-static bubble wrap and ships that way.

Same or next business day shipping from our Idaho warehouse. Honest pricing, no nonsense.

Product Overview

The MC74HC02AN is a quad 2-input NOR gate from ON Semiconductor, built on the 74HC high-speed CMOS process and supplied in a 14-pin plastic DIP for through-hole boards, sockets, and breadboards. Four independent NOR gates sit in the one package: each output goes to logic high only when both of its inputs are low, and drops to logic low if either input goes high. The listing's original specification gives an operating range of 2 to 6 volts, which is typical of the 74HC family and its combination of fast switching with low static power draw. The part on the photo carries the ON logo cast into the plastic alongside the full MC74HC02AN marking, so the identity is legible in hand and not a guess from a bin label. Buyers cross-shopping will also see this device written as 74HC02, HC02, and MC74HC02A.

Key Features

• Package: 14-pin plastic DIP, through-hole, socket friendly
• Logic family: 74HC high-speed CMOS
• Operating voltage range: 2 to 6 V per the original listing specification
• Output behavior: high only when both inputs are low
• Condition: used pull, all leads straight and bright
• Quantity available: one piece, sold each

Applications

• Repair technician replacing a failed NOR gate on a legacy digital control board that is no longer supported
• Hobbyist breadboarding a set-reset latch or simple gating logic from a single quad package
• Lab engineer building a one-off glue-logic fixture and needing exactly one chip, not a tube of twenty-five
• Restorer matching a through-hole 74HC part on an older instrument rather than adapting a surface-mount substitute

Frequently Asked Questions

What is the CPCY0726G line under the part number?

That is the manufacturer's own lot and date code as printed on the package, and it is transcribed here exactly as the photograph shows it. It identifies the production run, not the device type. The device type is the MC74HC02AN on the line above it.

Are the pins in usable shape for soldering or socketing?

Yes, as photographed. All fourteen leads are present, straight, aligned in their rows, and bright, with no solder blobs or residue. A part pulled from a socket comes out clean like this. Look at the photo and judge the leads for yourself before you order.

Has this chip been electrically tested?

No. It is sold as a used pull with no functional or parametric testing performed. Confirm the pinout, voltage range, and timing against the current ON Semiconductor datasheet before you commit it to a design.

Is this the same as a 74HC02 from another manufacturer?

The 74HC02 designation is an industry-standard quad 2-input NOR gate, and the MC prefix marks this one as the ON Semiconductor version. Pin functions across the family are standard, but always verify the specific datasheet parameters that matter to your circuit before substituting.

It is a used pull and untested - so what am I actually buying here?

You are buying the exact chip in the photograph: one 14-pin DIP, marked MC74HC02AN and CPCY0726G, leads straight and clean, no electrical testing done. The photo is the specification. What you are taking on is the small risk that comes with any untested pull, and what you get for it is a legible, identifiable, individually inspected through-hole part instead of a mystery chip out of a scrap bag. Shipping is a flat $8, free once your order passes $28, and orders leave our Idaho warehouse the same or next business day.

The NOR gate is the one piece of logic every other gate can be built from, which is why a single quad package still turns up as the fix for a board nobody manufactures anymore. Unwrap it from the pink bubble, drop it in the socket, and let your circuit have the last word.
