The recommended PCB layout for the TLP155E involves keeping the input and output traces as short as possible, using a ground plane to reduce noise, and placing a 0.1uF bypass capacitor between the VCC pin and ground.
The TLP155E requires a single 3.3V or 5V power supply, and it's recommended to power the device after the input signals are stable. There are no specific power sequencing requirements, but it's recommended to power the device slowly (within 10ms) to prevent latch-up.
The maximum cable length supported by the TLP155E depends on the specific application and the type of cable used. However, as a general guideline, the device can support cable lengths up to 10 meters at a data rate of 100 Mbps.
To troubleshoot issues with the TLP155E, check the power supply voltage, ensure proper input signal levels, and verify the PCB layout and routing. Also, check for any damage to the device or the PCB. If the issue persists, consult the datasheet and application notes or contact Toshiba support.
The TLP155E is a TTL-compatible device, but it can also be used with CMOS logic families. However, the input signal levels and voltage thresholds may need to be adjusted accordingly.
