1. All parameters specified for Ta = 25°C, Vcc = 15Vdc, Rosc= 75KΩ (to Vref), Cosc = 1800pF, and all Phase Outputs unloaded (Ta-Tj).

All negative currents shown are sourced by (flow from) the pin under test.

2. Either ISH or ISL may be driven over the range shown.

3. Bold parameters tested over temperature range.

4. Pulse Test: Pulse Width £ 300 µSec,Duty Cycle £ 2%.
