Need help to replace 555
Hi guys, Can anyone help me please replace the NE555 IC in this circuit by MIC1555. I need to modify also the Voltage to 18v thank you.
The circuit above represents a PWM generator where the user can adjust the frequency separately from the duty cycle and vice versa, but the disadvantages of this circuit are the limitation of the NE555 that is manifested in low frequency 100khz and a high rise/fall time of 100ns to 300ns. And since the MIC1555 is a member of the family of the most known IC timer the 555 I thought that it can replace the NE555 with your help.
It's pretty much just a direct substitute for the other 555 chip.
Obviously you need to take care not to overload the other parts when you increase the supply voltage.
The new part's 5Mhz max means it should be able to go about 5 times faster than the NE555 (which topped out at about 1MHz)
member of the family
There's not really a family, 555 is more a user interface standard than a lineage.
