The TOTX178A is a fiber optic transmitting module designed for digital audio equipment. It conforms to the EIAJ CP‑1201 standard and includes a differential LED driver and self‑tapping mounting holes.
The document lists electrical, optical and mechanical characteristics, recommended operating conditions, board layout guidelines, and safety precautions such as soldering limits, voltage limits, and proper disposal of GaAs‑based LEDs.
| Storage Temperature | -40 °C to 70 °C |
|---|---|
| Operating Temperature | -20 °C to 70 °C |
| Supply Voltage | -0.5 V to 7 V |
| Input Voltage | -0.5 V to Voc + 0.5 V |
Use a supply voltage of 5 V with a tolerance of ±0.25 V and never exceed the maximum rating of 7 V.
Solder at 260 °C or less for no more than ten seconds and avoid flux contacting the emitting surface.
The module can be stored between –40 °C and 70 °C.
Yes, the LED contains GaAs, which is toxic; avoid breaking or pulverizing the device and follow proper disposal procedures.
