I stand corrected. On reflection, I seem to remember a lower supply voltage on the RTL, although 3.6 doesn't ring a bell. Do remember that it was very temperamental logic family. Used to get lots of catastrophic failures on the DMM product range (which I believe SD acquired from Fairchild).

It was an evolutionary step. RTL was a strange beast, and ran off of 3.6V. There is no inherent reason that there couldn't have been multiple families that used different supplies, but I only remember the 3.6V variety. -Chuck Harris Rob Kimberley wrote: > RTL and DTL used 5.0V.
