NOTES:
1. Currents flowing into device pins are positive. All voltages are referenced to ground unless otherwise specified. For ease of interpretation,
the parameter limit that appears in the MAX column is the largest value of the parameter, irrespective of sign. Similarly, the value in the MIN
column is the smallest value of the parameter, irrespective of sign.
2. All typicals are for VEE = –9V and TA = 27°C.
3. ITDC is measured as (VMAX + VMIN)/(2 x 25) where VMAX and VMIN are the max and min voltages at TXO with a 25Ω load between TXO and
GND. ITAC is measured as (VMAX – VMIN)/(2 x 25).
4. The TXO pin shall continue to sink at least ITDC min when the idle (no signal) voltage on this pin is –3.7V.
5. Collision threshold for an AC signal is within 5% of VCD.
6. Measured on secondary side of isolation transformer. The transformer has a 1:1 turns ratio with an inductance between 30 and 100µH at
5MHz.
7. Measured as the voltage difference between the RX pins or the CD pins with the transformer removed.
8. Not 100% tested in production.
