The MC34063A/E series is a monolithic control circuit which delivers the main functions for DC-DC voltage converting. The device contains an internal temperature compensated reference, comparator, duty cycle controlled oscillator with an active current limit circuit, driver and high current output switch. Output voltage is adjustable through two external resistors with a 2% reference accuracy. Employing a minimum number of external components, the MC34063A/E device series is designed for step-down, step-up and voltage-inverting applications.

The MC4558 is a high performance monolithic dual operational amplifier. The circuit combines all of the outstanding features of the MC1458, and in addition possesses three times the unity gain bandwidth of the industry standard.

The MD1802FX is manufactured using Diffused Collector in Planar Technology adopting new and enhanced high voltage structure. The new MD product series show improved silicon efficiency bringing updated performance to the Horizontal Deflection stage.

The devices are manufactured in planar technology with "base island" layout and monolithic Darlington configuration.

The device is manufactured in planar technology with "base island" layout. The resulting transistor shows exceptional high gain performance coupled with very low saturation voltage.

The MJD340 and MJD350 form complementary NPN -PNP pairs. They are manufactured using Medium Voltage Epitaxial-Planar technology, resulting in a rugged high performance cost-effective transistor.
