Input Current

OSC, Detect – VIN = VSS or VDD

Low-Supply Trip – VIN = VSS or VDD

Feedback – VIN = VSS or VDD

Low -Level Input Current

Test – VIN = VSS or VDD

Pull-Down Current

Test – VIN = VDD

I/O – No Local Smoke, VIN = VDD

I/O – No Local Smoke, VIN = 17 V

Low-Level Output Voltage

LED – IOUT = 10 mA

Silver, Brass – IOUT = 16 mA

High-Level Output Voltage

Silver, Brass – IOUT = 16 mA

Output Voltage (For Line Regulations, See Pin Descriptions)

Strobe – Inactive, IOUT = -1 µA

Active, IOUT = 100 µA to 500 µA (Load Regulation)

IRED – Inactive, IOUT = 1 µA

Active, IOUT = 6 µA (Load Regulation)

High-Level Output Current

I/O – Local Smoke, VOUT = 4.5 V

I/O – Local Smoke, VOUT = VSS (Short Circuit Current)

Off-State Output Leakage Current

LED – VOUT = VSS or VDD
