What Are the Pin Functions of TL494

 TL494 is one of the IC components, the following is its pin connections:

1,16 AND 2,15 PIN are the feet of error amplifier 1 and 2′s  input and inverting input; 3 pin is the feedback input terminal; 4 feet is the dead time control terminal; 5,6 feet respectively, then RC oscillator timing capacitor and resistor; 7 feet grounded; 8,9 feet 11,10 feet are two internal drive transistor’s collector and emitter; 12-pin power supply positive terminal; 13 pin of TL494 is the output state control terminal, When the 13 foot high, two internal drive transistors alternately turn, when the 13 pin is low, while the two internal drive transistor turned on or off, this time can only control a switch. 14-pin 5V output of the IC internal reference voltage output.
