MM74C02J Quad 2-Input NOR Gate integrated circuit in a ceramic package, (indicated by the J in the part no. these were higher spec than the ordinary plastic type, intended for high-reliability or military/industrial environments).
From the vintage 74C CMOS logic family.
General Description
These logic gates employ complementary MOS (CMOS) to achieve wide power supply operating range, low power con-sumption, high noise immunity and symmetric controlled rise and fall times. With features such as this the 54C/74C logic family is close to ideal for use in digital systems. Func-tion and pin out compatibility with series 54/74 devices mini-mizes design time for those designers already familiar with the standard 54/74 logic family. All inputs are protected from damage due to static dis-charge by diode clamps to VCC and GND.
Part Breakdown
- MM: National Semiconductor / Fairchild prefix for standard CMOS devices.
- 74C: The logic family. It uses CMOS technology but features the exact same pinout arrangement as the classic standard 7400 TTL series.
- 02: The logic function, which represents a Quad 2-Input NOR gate (four independent NOR gates inside one chip).
- J: The package type, denoting a Ceramic Dual In-Line Package (CDIP), typically a 14-pin hermetically sealed package used for high-reliability or military/industrial environments.
Key Specifications
- Supply Voltage Range: 3V to 15V (giving it a much broader operational range than standard 5V TTL).
- Low Power Consumption: Typically around 10 nW per package, making it highly efficient for static conditions.
- High Noise Immunity: Typically 0.45 × \(V_{CC}\).
- Pinout: 14 Pins total (\(V_{CC}\) at pin 14, GND at pin 7).

PLEASE NOTE!
These parts came to us as part of a lot of surplus stock from a large distribution Co. and have been kept in storage for a time, we have therefore classified them as ‘new other’, they are however pristine, stored with us still in their original packaging/tubes, and, as with all our products they come with a full guarantee.
If you have similar items to this, or indeed any electronic components that are surplus to requirements please contact us with details.
