SPECIFICATION NOTES:
1. All parameters specified for Ta = 25
°C, Vcc = 15Vdc, Rosc = 75K
(to Vref), Cosc = 1800 pF, 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 at -55
°C, 25°C, 125°C for SFB.
4. Pulse Test: Pulse Width < 300
Sec, Duty Cycle < 2%.
