I need to make up a reset circuit to reset, on power on, a Z80 (old

40-pin DIP type) and a few TTLs. I don't want to make up some circuit using TTLs and resistors, caps, etc, I simply want to buy an off the shelf part which ONLY requires +5 volts, GND and a wire to connect it to the reset line on my PCB. I don't want to have to wire up other parts to it to get it to work.

Does such a modern part exist?

Thanks

Yes, there are many of them. Some may require a pair of resistors to set the voltage.

For example, go to ti.com On the left column, click the Power Managment link then click Supervisory Circuits(Voltage Supervisors) (237) (it's about half way down the page)

These are my opinions, not necessarily my employer\'s. I hate spam.
