Notes:
1. Logic 1 input will turn the light on and the logic 0 will turn the light off.
2. This is a digital input for the transmitter output power selector. RCN < 17.32 k will set the
transmitter to normal output power. RCR > 25.65 k will set the transmitter to reduced output
power. RCN/RCR is connected between CONT input and VCCT.

Notes:
1. This output is logic 1 high if the receiver is asleep for no light input, and logic 0 low if the
receiver is awake for valid light input levels.
2. TTL compatible data output.

Notes:
1. Absolute Maximum Ratings are those values beyond which damage to the device may occur if these limits are exceeded for other than a short
period of time. See Reliability Data Sheets for specific reliability performance.
2. Measured 1 cm outside of MOST optical connector housing (header) on a MOST application PCB. The optical components (EOC and OEC) are
inside the header connector assembly composed of the plastic housing and EMI shield, that is, airflow is restricted to natural convection.
3. The CONT input is a digital function. An open circuit will select lower (normal light output -3 dB), and a short circuit to VCCT will select normal light
output power. This makes the LED meet eye safety under this fault condition.
4. A safety resistor of 50 W (minimum) is to be connected between Data Out and the receiving circuitry. The receiving circuitry must be powered up
within 50 ms after Mode Out goes low to prevent permanent damage to the OEC.
