10.4 DC Operating Characteristics
This section lists the ICS1893 DC operating characteristics.
10.4.1
DC Operating Characteristics for Supply Current
lists the DC operating characteristics for the supply current to the ICS1893 under various
conditions.
Note:
All VDD_IO measurements are taken with respect to VSS (which equals 0 V).

Parameter
Supply Current†
† These supply current parameters are measured through VDD pins to the ICS1893. The supply current
parameters include external transformer currents.
‡ Measurements taken with 100% data transmission and the minimum inter-packet gap.
10.4.2
DC Operating Characteristics for TTL Inputs and Outputs
lists the 3.3-V DC operating characteristics of the ICS1893 TTL inputs and outputs.
Note:
All VDD_IO measurements are taken with respect to VSS (which equals 0 V).
