2.5/3.3V Bidirectional LVTTL I/O with Programmable Drive, Schmitt Trigger & Pull-Up/Down
LVTTL33 cell belongs to Sankalp’s General Purpose IO library in 65nm TSMC G+ process. It is a LVTTL bidirectional cell which operates on 3.3 V or 2.5 V supply, at frequencies upto 200MHz (400 Mbps). Programmable Drive strength, Schmitt trigger and Pull-up/down, are some of the salient features for this cell. Cell dimensions are 25um x 170um.
Features
