Product Overview
Signetics 74S00N (marked with OEM designation 2600-1487) is a high-speed Schottky TTL quad two-input NAND gate housed in a standard 14-pin dual in-line package. Manufactured with a 1980 date code, this component serves as a direct drop-in logic replacement for vintage industrial equipment, test instruments, and legacy computing hardware.
Key Features
- Logic family: 74S Series Schottky TTL
- Function: Quad 2-input NAND gate (4 independent gates)
- Supply voltage: 5.0 V nominal (4.75 V to 5.25 V operating range)
- Package type: 14-pin plastic DIP through-hole
- Operating temperature range: 0°C to 70°C commercial
- Markings: 2600-1487 and 74S00N with 8039 date code
Applications
- Repairing legacy automation controls and vintage computing equipment requiring original Schottky switching speeds.
- Breadboarding hobbyist synthesizer circuits, retro gaming hardware, and discrete logic designs.
Frequently Asked Questions
Is the 2600-1487 part number identical to standard 74S00 logic?
Yes. The chip bears both the 2600-1487 OEM designation and the standard Signetics 74S00N identification. It operates as a standard commercial 74S00 quad 2-input NAND gate.
Has this integrated circuit been electronically tested?
Visual inspection only. Function testing has not been performed on this pull.
Why purchase this single component instead of a surplus bulk lot?
Buying an individual, photographed unit lets you source the exact part needed for a repair without paying for extra components you do not need. Shipping is $8 flat rate, free once the order passes $28, and orders leave our Idaho warehouse the same or next business day.
Schottky TTL was built for an era when trimming nanoseconds off gate propagation meant real progress. Pop it into the board, power the rail, and restore original timing to your vintage circuit.
