Notes:
1. Minimum voltage at OUT+ > 0.7V.
2. The current through the laser in this state can be made negligible by adding a 1kΩ or less resistor in parallel with the laser.
3. The M02094 is designed to drive 25Ω loads. External resistance should be added in series or parallel to the Laser to create this load impedance. In
common cathode mode, 50Ω resistors internal to the M02094 are in parallel with the laser.

Safety Logic Timing
(V_CC = 3.05 V to 3.55V or 4.7V to 5.5V, T_A = -40 °C to +95 °C, unless otherwise noted)
Typical values for common anode are at V_CC = 3.3 V, IBOUT_CA = 20 mA, I_MOD = 20 mA, T_A = 25 °C, unless otherwise noted.
Typical values for common cathode are at V_CC = 3.3 V, IBOUT_CC = 5 mA, I_MOD = 5 mA, T_A = 25 °C, unless otherwise noted.
