Schmitt Trigger Input
Intel® Cyclone® 10 LP devices support Schmitt trigger input on the TDI, TMS, TCK, nSTATUS, nCONFIG, nCE, CONF_DONE, and DCLK pins. A Schmitt trigger feature introduces hysteresis to the input signal for improved noise immunity, especially for signals with slow edge rate.
Symbol | Parameter | Condition (V) | Minimum | Unit |
---|---|---|---|---|
