Notes
4. Specified only for temperatures below 0°C.
5. Total Receiver operating current (assuming that the Transmitter is not activated) can be found by adding I
CCS
+ I
CCR
+ x * I
CCE
; where x is 2 if the ROUT± outputs
are not activated and 3 if they are activated.
Total Transmitter operating current (assuming that the Receiver is not activated) can be found by adding I
CCS
+ I
CCT
+ x * I
CCE
; where x is 1 if the TOUT± outputs
are not activated and 2 if they are activated.
Total device power (assuming that the Transmitter and the Receiver are activated) can be found by adding I
CCS
+ I
CCR
+ I
CCT
+ x * I
CCE
; where x represents
the number of ECL output pairs activated.
6. Tested initially and after any design or process changes that may affect these parameters.
