Hitachi, Ltd. is a Japanese multinational conglomerate company.

History[edit]

Hitachi was founded in 1910 by electrical engineer Namihei Odaira in Ibaraki Prefecture, northeast of Tokyo. Hitachi started already in 1965 the development of Integrated Circuits (ICs), based on technology from RCA in the USA.

The first products of the HD100 Series were designed in ECL (Emitter-coupled Logic) technology, a high-speed bipolar transistor logic family using a 15 um manufacturing process and used in October 1966 with Sharp's CS-31A, the World’s first electronic calculator incorporating ICs.

Hitachi followed soon with the HD700 Series, a family of SSI (Small Scale Integration) ICs in PMOS (p-channel Metal-oxide Semiconductor) technology and consisting of simple inverters, logic gates, flip flops and 4-bit to 16-bit shift registers, packaged in 10-pin and 12-pin metal can housings (TO-100 and TO-101, respectively) and operated with a single 24V supply. These kinds of chips, commonly referred as JMOS devices for Japanese MOS, were manufactured around 1966 to 1971 not only by Hitachi, but with similar or identical functionality, from companies like Mitsubishi, NEC and Toshiba, too and provided similar functionality to the DTL and TTL Logic Families introduced in the Western world.
