Silicon die of the first 555 chip (1971) Die of a CMOS NXP ICM7555 chip. The timer IC was designed in 1971 by Hans Camenzind under contract to Signetics. [3] In 1968, he was hired by Signetics to develop a phase-locked loop (PLL) IC. He designed an oscillator for PLLs such that the frequency did not depend on the power supply voltage or ...
Signetics Corporation was an American electronics manufacturer specifically established to make integrated circuits. [1] Founded in 1961, they went on to develop a number of early microprocessors and support chips, as well as the widely used 555 timer chip.
Chip-on-glass (COG), a variation of COB, where a chip, typically a liquid crystal display (LCD) controller, is mounted directly on glass. Chip-on-wire (COW), a variation of COB, where a chip, typically a LED or RFID chip, is mounted directly on wire, thus making it a very thin and flexible wire.

An external pass transistor is required to complete an on-chip voltage regulator, which supplies 3V to selected areas of the chip. This helps contain the total current drain to less than 450 mA . Clock requirements are met by connecting an 8 MHz crystal directly to two pins.
