TLP250H(LF1,F) - Toshiba

TLP250H(LF1,F) Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the TLP250H?
  Toshiba recommends a PCB layout with a ground plane underneath the IC, and a 10nF to 100nF decoupling capacitor between VCC and GND, placed as close as possible to the VCC pin. Additionally, the input and output traces should be kept short and away from noise sources.
• How do I ensure reliable operation of the TLP250H in high-temperature environments?
  To ensure reliable operation in high-temperature environments, it is recommended to derate the output current and voltage according to the temperature derating curve provided in the datasheet. Additionally, ensure good thermal conductivity between the IC and the PCB, and consider using a heat sink if necessary.
• What is the maximum allowable voltage on the input pins of the TLP250H?
  The maximum allowable voltage on the input pins of the TLP250H is 5.5V, regardless of the VCC voltage. Exceeding this voltage may cause damage to the IC.
• Can I use the TLP250H as a level translator between 3.3V and 5V logic levels?
  Yes, the TLP250H can be used as a level translator between 3.3V and 5V logic levels. However, ensure that the input voltage is within the recommended range of 2.5V to 5.5V, and that the output voltage is within the recommended range of 2.5V to VCC.
• What is the typical propagation delay of the TLP250H?
  The typical propagation delay of the TLP250H is around 10ns to 20ns, depending on the output load and the input signal transition time. Refer to the datasheet for more detailed information on propagation delay.
