1 Temperature range TMIN to TMAX is 40°C to +85°C. The minimum/maximum specifications are guaranteed over this range.
2 Guaranteed by characterization.
3 TTL input values are 0 V to 3 V, with rise/fall times ≤3 ns, measured between the 10% and 90% points.
4 SDP timing figures obtained using default drive strength value (0xD5) in Register 0xF4.
