DC and AC parameters
This section summarizes the operating and measurement conditions, as well as the DC and
AC characteristics of the device. The parameters in the following DC and AC characteristic
tables are derived from tests performed under the measurement conditions listed in the
Table 5: Operating and AC measurement
operating conditions in their projects match the measurement conditions when using the
quoted parameters.
Table 5.
1. Output Hi-Z is defined as the point where data is no longer driven.
2. Supply voltage for SOH28 is 3.3V to 5.5V.
