ACCEL INDUSTRIAL LIMITED

Thousands of tiny transistors, diodes, resistors and capacitors are fabricated on a semiconductor wafer forms integrated circuit.there are two types of ic, CMOS ic and digital ic. MOSFETs come in four different types. They may be enhancement or depletion mode, and they may be n-channel or p-channel.There are also logic-level MOSFETs and normal MOSFETs.

H11F3300, H11F2W, H11F2300, H11F1W, H11F1SD, H11F1S
Produced by Fairchild
6-Pin DIP Bilateral Analog FET Output Optocoupler.
The H11F series consists of a Gallium-Aluminum-Arsenide IRED emitting diode coupled to a symmetrical bilateral silicon photodetector.The detector is electrically isolated from the input and performs like an ideal isolated FET designed for distortion-free control of low level AC and DC analog signals. The H11F series devices are mounted in dual in-line packages. H11F3300, H11F2W, H11F2300, H11F1W, H11F1SD and H11F1S can work As a variable resistor: Isolated variable attenuator, Automatic gain control, Active filter fine tuning/band switching. they can also work as a As an analog switch: Isolated sample and hold circuit, Multiplexed, optically isolated A/D conversion.
