TABLE IF NOTES:

1/ TA nom = 25ºC, TA max = 125ºC, and TA min = -55ºC unless otherwise noted. Switching specifications are tested with CL = 15 pF, and CMOS signal

levels, unless otherwise noted VDD1 nom = 1.8 V, VDD1 max = 1.9V, VDD1 min = 1.7V and VDD2 nom = 5 V, VDD2 max = 5.5 V, VDD2 min = 4.5V .

2/ Parameter is part of device initial characterization which is only repeated after design and process changes or with subsequent wafer lots.

3/ Parameter is not tested post irradiation

4/ tPSK is the magnitude of the worst-case difference in tPHL or tPLH that is measured between units at the same operating temperature, supply voltages,

and output load within the recommended operating conditions.

5/ VIx refer to the voltage input signals of a given channel (A, B, C, or D).

6/ IOx refer to the output current of a given channel (A, B, C, or D).

7/ VDDx refers to the power supply on either side of a given channel (A, B, C, or D).

8/ 150 Mbps is the highest data rate that can be guaranteed, although higher data rates are possible

9/ Do not exceed Do not exceed VDD2nom where VDD2 = 5V at T = -55°C when all four channels are running in parallel. Device instability may occur.

10/ V_Exrefers to V_E1and V_E2
