Burn-In Circuit

80C286/883

NOTES:

8. Supply Voltage: VDD = 5.5V, VSS = 0.0V.

9. Input Voltage Limits: VIL (Maximum) = 0.8V, VIH (Minimum) = 2.0V

10. Component Values: RC = 1kâ¦ Â±5%, RI = 10kâ¦ Â±5%, RO = Two Series 2.7kâ¦ Â±5%

11. Capacitor Values: C1 = 0.1 Microfarads

12. Oven Type and Frequency Requirements: Wakeï¬eld Oven Board f0 = 100kHz, f3 = 12.5kHz,

f4 = 6.25kHz, f5 = 3.125kHz, f7 = 781.25Hz.

13. Special Requirements: (a) ELECTROSTATIC DISCHARGE SENSITIVE. Proper Precautions Must be Used When Handling Units. (b) All Power Supplies

Must be at Zero Volts When the Boards are Inserted into the Ovens. (c) When Powering Up, the Inputs Must be Held Below the VDD Voltage. (d) If an

Excessive Current is Indicated at Final Inspection, Check to See if a Part is Inserted Backwards or is Latched Up.
