Another advantage to BiCMOS over those listed is: 5. Schottky clamp diodes (reduced ringing). I have heard system designers say they would sell their soul for a process that would just allow Schottky clamp diodes. You can design a CMOS driver w/ a low voltage swing, controlled edge rates and fairly high drive (not as high as BiCMOS but..). No question it burns area, but then area is cheap (cheaper then a new process, any body know how many more steps a BiCMOS process has over a CMOS process ? Steps cost money and reduce yield). -- ----------------------------------------------------------------------------- Tom Shott INTeL, 2111 NE 25th Ave., Hillsboro, OR 97123, (503) 696-4520 toms@omews44.intel.com OR toms%omews44.intel.com@csnet.relay.com INTeL..
