Product Overview
Fairchild 26001487 in a standard plastic DIP-14 package. Features vintage 1976 production markings and documented functional equivalence to the industry-standard SN74S00N quadruple 2-input positive-NAND gate. Custom house-numbered logic parts of this era were manufactured for specific computer, instrumentation, and telecommunications OEMs requiring high-speed Schottky TTL logic.
Key Features
- Dual in-line 14-pin plastic package (DIP-14)
- Through-hole mounting with standard 0.1-inch (2.54 mm) pin spacing and 0.3-inch row width
- Intake documented functional equivalent to standard SN74S00N quad 2-input NAND gate
- Fairchild "F" logo and 1976 date code (7606) stamped on package body
- Body length measures approximately 19 mm
Applications
- Replacing failed OEM-marked logic chips in vintage mid-1970s test gear, terminals, and minicomputer boards
- Benchtop breadboarding and prototyping requiring period-correct Schottky TTL logic
- Retrocomputing restoration projects needing authentic 1976 semiconductor date codes
Frequently Asked Questions
What is part number 26001487?
This number represents an OEM customer part number manufactured by Fairchild Semiconductor. The intake record notes it as functionally equivalent to the standard SN74S00N quadruple 2-input positive-NAND gate.
Has this integrated circuit been tested on a logic analyzer?
Visual inspection only. Electrical testing has not been performed on this specific pull.
Why buy a single vintage pull instead of a full surplus tube?
You receive the exact, individually photographed 1976 Fairchild chip shown here to fix one specific board, without buying unnecessary bulk stock. Orders ship same or next business day from our Idaho warehouse for an $8 flat rate, or free when your cart reaches $28.
Old TTL logic chips have a distinct honest presence that modern SMD packages just cannot replicate. Plug it into the socket, power the rail, and bring vintage digital hardware back into service.
