I am designing a sub-circuit on in a serial communication device. I want to make sure that the circuit's time constant is shorter than the time it takes to power up a circuit board. What is a reasonable lower limit on the time it takes to power up a 1.5V supply? This circuit will be used in a HyperTransport subsystem. -------------------------------------------------------------- | Bill Cohen | Toshiba America Electronic Components, Circuit Design Group | email: wcohen@xxxxxxxx -------------------------------------------------------------- ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
