Optoisolators - Logic Output form part of a range of components designed to provides electric insulation between input and output, and the 6N140TXVB form part of this range. While this component is mainly used in Consumer and Automotive circuitry, it has a wide range of applications both in commercial and industrial related circuits.

The 6N140TXVB is an opto-isolator that consists of a photo transistor with internal gallium arsenide infrared LED. This component is a 4 pin device with photo collector, base and two emitter pins, designed to couple digital logic circuitries. The LED used emits infrared light when positively biased, and the transistor in the device turns it off when negatively biased. This transistor output is effective at switching any potential signal from input to output with high speed and accuracy while providing complete isolation between the two circuits.

This device has an open-collector configuration, which means that the collector pin is not connected to any other pin. This allows the component to control various current loads larger than the rated current or voltage of the device, and also serves to protect the transistor from excessive voltages. The 6N140TXVB has a photo-collector current of 30 mA, and a voltage rating of up to 30 volts.

The 6N140TXVB is primarily used in Consumer and Automotive circuitry, where it can be used to optically couple digital input and output signals. This isolator offers superior protection from potential electricity faults that may occur, and is extremely resistant to electrical noise. This makes it ideal for use in protection circuits, safety circuits and industrial automation. In addition, thanks to its small size, it can be used in confined spaces such as test boards, embedded circuitries and even in personal computers.

The 6N140TXVB can also be used as an amplifier, as the signal from the LED is amplified to a level suitable for any digital circuit. The input and output voltages are converted into logic signals, allowing high-speed signal transmission. Aside from these, the 6N140TXVB is also used for edge detection, smooth switching, surge protection and in high frequency modulation.

The 6N140TXVB is a versatile opto-isolator, and is suitable for a wide range of applications. However, it is important to note that the component is limited by the speed of the LED. The durability and reliability of this component is good too, and it can be expected to last up to 100,000 hours with appropriate operating conditions.
