The ideaEdit

The production of a cheep and efficient early era 3 transistor microchip for basic electrical functions.


The then standard silicon\germanium etching process.


Philips TAA320 integrated circuit.
Category. Statistic.
Designed in. 1964.
Made in. About ~1964.
Transistors per chip. 3.
Power supply. Low or battery power.
Still in use. Yes, but with increased efficacy and reduced size.
Nationality. Dutch.

It was meant to replace transistors like the American 2N34 PNP Germanium Alloy Junction Transistor, so the circuit would have 1, not 3 cans on it!

Like all ICs, it is made to a JEDEC standard and ID numbering code after 1953. It was one of the Netherlands's first moves in to the modern electrical business and it was seen as a national icon at the time.


A 3 legged metallic TO-18 transistor packing unit shell. T-18 stands for Transistor Outline Package, Case Style 18. It was often mistaken for the 2N107 germanium alloy junction PNP transistor (General Electric (GE)) transistor at the time.
