DC OPERATING CHARACTERISTICS
NOTES
1. Currents into device pins are positive, currents
2. All typicals are for VEE = -9V, Ta = 25°C.
3. -8.55V > VEE > -9.45V.
4. The voltage on TXO is -4V < V(TXO) < 0.0V.
5. The AC current measurement is referenced to
out of device pins are negative. If not
specified, voltages are referenced to ground.
