2pcs 5kHz~400kHz TP353 NE555 square wave output pulse generator module sources A functional description: 1. After add the power output end of the output pulse signal, the amplitude is approximately equal to the power supply voltage. 2. The output duty cycle regulation, in the process of adjusting the frequency output signal pulse rate basically stable (50% 65%). 3. The frequency by bringing more ring potentiometer adjustment, adjustment range: 5kHz~400kHz 2. Power supply: Power supply voltage dc 5 v to 15 v, 5 v space-time working current 2.5 mA, 12 v space-time working current 6.5 mA. 3. Output drive current: 200 ma MAX. 4. Application: Used as signal source in the circuit 5: method of use: 1. Connect power can work. 2. When used in the power the power of the termination of a 0.1 uf filter capacitor to be stable in their work. 3. The clockwise adjust potentiometer, increased frequency, counterclockwise to adjust potentiometer, a decrease in frequency. 6. Size: Do not contain pin size 13 mm x 10 mm x 8 mm. Pin spacing of 2.54 mm. 7. Note: 1. The above parameters are measured under 5 v voltage, there may be different in other voltages. 2.
