HCF4049 DATASHEET PDF

The IC consists of six NOT gate inside it and having a high input supply voltage with a maximum current rating of 1mA at 18v. The main use of this IC is to create a voltage multiplier circuit by simply adding resistor, capacitor, and diode with it. It also used for the conversion of high logic levels to low. Also you can drive two TTL loads with it. The IC is having high current sink as the input voltage the increase the output current sink value will increase, at 15v the current sink value is 26mA. It can also be useful in making various projects like simple LED torch light, Automatic Street light, magic eye, and automatic guest detector at home door.

It includes the six independent inverters inside. The input-signal high level VIH can exceed the VCC supply voltage when these devices are used for logic-level conversions. The Maximum power supply must not exceed 18 volts. CD on Amazon. The circuit we use a little equipment, just add a resistor and capacitor are the only one, It uses less energy. The output frequency is relatively constant, the rate of change in frequency of the power supply voltage is less.

Pls i will need a help in building my own inverter. I have the circuit but i need for efficient pulse generator with a variable resistor to control the trigger speed to the thyristor gate. Could you please be specific re the frequencies — I need a variable range of 1. Also — an amplitude of 9 volt.

What would be the average current in such a case? I need to build a circuit contain a crystal oscillator square wave with 10 : 90 MHZ with 12 V input and contain all methods to controlling increase and decrease i.
