Programmable Timers and Oscillators are components that are widely used in many electronic circuits, often in the form of a timing circuit. These devices are typically used as basic building blocks in digital clocks, electronic watches, timers, and other timing-related circuits. This article will focus on the 8N4SV75LC-0094CDI Programmable Timer and Oscillator specifically, including its application field, working principle, and associated product information.

Application Field

The 8N4SV75LC-0094CDI is a general-purpose programmable timer and oscillator designed for use as an oscillating source in consumer, automotive, and industrial applications. It is suitable for timing applications in consumer products such as LCD television, computer motherboards, and various other consumer electronics. It is also applicable to automotive applications such as motor control, air conditioning control, and other automotive systems.

The 8N4SV75LC-0094CDI is also suitable for industrial applications such as factory automation, power control, and alarm systems. It is highly reliable and features a wide operating temperature range, making it an ideal choice for mission-critical applications in harsh environments.

Working Principle

The 8N4SV75LC-0094CDI Programmable Timer and Oscillator is a two-stage, dual-output device that uses a voltage-controlled oscillator (VCO) driven by a comparator. The VCO is a silicon-controlled oscillator (SOS) composed of four transistors and two resistors. The output frequency is determined by the voltage applied to the control input of the VCO, and can be adjusted by varying the R1 and R2 resistors. Additionally, the input voltage can be further adjusted using external capacitors.

When used as an oscillator, the device will generate a continuous square waveform at its output stage. The frequency can be adjusted by varying the control voltage of the VCO as well as the variables R1 and R2. Depending on the configuration of the circuit, the frequency range of the output waveform can be between 5 Hz to 500 KHz.

When used as a timer, the device will generate a pulse waveform at the output stage. The pulse width can be adjusted by varying the voltage to the input of the comparator, and can range from 0.1% to 99.9%. Additionally, the pulse rate of the output waveform can be changed by varying the resistors R1 and R2.
