Chapter 9 DC and AC Operating Conditions
9.4 DC Operating Characteristics
This section lists the ICS1893CF DC operating characteristics.
9.4.1 DC Operating Characteristics for Supply Current
Table 9-4 lists the DC operating characteristics for the supply current to the ICS1893CF under various
conditions.
Note: All VDD_IO measurements are taken with respect to VSS (which equals 0 V).

† These supply current parameters are measured through VDD pins to the ICS1893CF. The supply current
parameters include external transformer currents.
‡ Measurements taken with 100% data transmission and the minimum inter-packet gap.
9.4.2 DC Operating Characteristics for TTL Inputs and Outputs
Table 9-5 lists the 3.3-V DC operating characteristics of the ICS1893CF TTL inputs and outputs.
Note: All VDD_IO measurements are taken with respect to VSS (which equals 0 V).
