Guaranteed by characterization.
TTL input values are 0 V to 3 V, with rise/fall times of ≤3 ns, measured between the 10% and 90% points.
SDP timing figures obtained using default drive strength value (0xD5) in Register Subaddress 0xF4.
CP timing figures obtained using maximum drive strength value (0xFF) in Register Subaddress 0xF4.
