Product Overview
Fairchild 7404PC standard TTL logic integrated circuit containing six independent inverting gates in a 14-pin dual in-line plastic package. Operating on a nominal 5.0 V supply, it delivers standard digital logic inversion for repair benches, legacy digital hardware maintenance, and vintage computing projects.
Key Features
- Hex inverter configuration (6 independent NOT gates)
- Standard Transistor-Transistor Logic (TTL) architecture
- 5.0 V nominal operating voltage (4.75 V to 5.25 V range)
- 14-pin plastic dual in-line package (PDIP-14, 0.300-inch row spacing)
- Through-hole mounting style
- Commercial operating temperature range (0°C to +70°C)
- 1984 production date code (8437)
Applications
- Servicing legacy 1980s microcomputers, arcade PCBs, and digital control boards requiring original standard TTL logic speeds.
- Replacing failed inverters in 5 V bench supplies, clock pulse generators, and signal conditioning circuits.
- Breadboarding digital logic gates and hardware educational circuits in maker workspaces.
Frequently Asked Questions
What logic family is the 7404PC?
Standard TTL (bipolar transistor-transistor logic). It requires a regulated 5 V supply and provides standard TTL output levels.
What is the pin spacing for this package?
Standard 0.100-inch (2.54 mm) lead pitch with 0.300-inch (7.62 mm) row spacing, fitting 14-pin IC sockets and through-hole prototyping boards.
Why buy this individually tested pull instead of hunting down a bulk surplus lot?
When you are troubleshooting a single logic board or restoring vintage arcade hardware, you only need the exact chip in hand without paying for excess inventory you will never use. Standard shipping is an $8 flat rate, orders over $28 ship free, and all orders leave our Idaho warehouse the same or next business day.
Nothing beats the simplicity of an authentic 1980s TTL inverter when you are bringing old silicon back to life on the bench.
