DC OPERATING CHARACTERISTICS
(continued)
NOTES
1. Currents into device pins are positive,
currents out of device pins are negative. If not
specified, voltages are referenced to ground.
2. All typical 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
the DC current level.
6. Operating or idle state.
7. Test load as shown in Figure 2.
8. Device measurement taken in idle state.
9. This threshold can be determined by
monitoring the CD± output with a DC level in
RXI.
