Raytheon "RG202D" TTL Military Integrated Circuit (Mid 1960s)

Items #933 to 951

This gold-plated tie tack features an early TTL logic chip manufactured by Raytheon. The chip package never had it's hermetically sealed lid installed so clear viewing of the TTL circuitry and wire-bonding is possible.

Raytheon's "RG202D"  chip was a TTL (transistor-transistor-logic) monolithic integrated circuit chip featuring 4 transistors. The chip came encased in a 14-pin, gold and ceramic flat-pack package. It was produced specifically for the high-specification military / space market that required higher temperature tolerances.

TTL circuit technology was invented by James L. Buile of Pacific Semiconductors in 1961. In 1963, Sylvania announced the first of many chips that were to form their "SUHL" (Sylvania Universal High-level Logic) family, developed by Sylvania's Dr. Thomas A. Longo. SUHL TTL chips would also be second-sourced by Raytheon (RG / RF series - such as the chip in this tie tack) and by Texas Instruments (G / F series). SUHL chips were the world's first commercially successful TTL chips. SUHL TTL chips were also available in gold and ceramic DIP (dual-inline) packaging.
