1) 0 â¦C ⤠TC ⤠70 °C (comm.); -25 °C ⤠TC ⤠85 °C (ext.); All voltages referenced to VSS. VSS and VSSQ must be at same potential.
2) VIH may overshoot to VDD + 0.8 V for pulse width < 4 ns; VIL may undershoot to -0.8 V for pulse width < 4 ns.Pulse width measured at 50%
with amplitude measured between peak voltage and DC reference level.
