Frequent questions

  • [FAQ] What is the maximum trace length ground-level translators can drive?

    FAQ: Logic and Voltage Translation > Ground-Level Translators >> Current FAQ The maximum trace length that ground-level translators (as well as logic devices) can drive is 60 mm. This is a safe trace length for most devices to drive across the majority…

  • [FAQ] Is DC ground shifting possible when both supplies are connected together?

    FAQ: Logic and Voltage Translation > Ground-Level Translators >> Current FAQ To use the ground shift capability, voltage supplies need to be isolated and fall within the recommended operating conditions. Let’s use the figure above as an example…

  • [FAQ] Can I generate a negative PWM signal from a positive PWM signal?

    Other Parts Discussed in Thread: TXG8041 FAQ: Logic and Voltage Translation > Ground-Level Translators >> Current FAQ A negative signal can be generated from ground-level translators as long as the user’s system has a negative supply rail. To prevent…

    FAQ: Logic and Voltage Translation > > Current FAQ [FAQ] What are the differences between Ground-Level Translators and Digital Isolators? [FAQ] Can I generate a negative PWM signal from a positive PWM signal? [FAQ] Is DC ground shifting possible…

  • [FAQ] What are the differences between Ground-Level Translators and Digital Isolators?

    FAQ: Logic and Voltage Translation > Ground-Level Translators >> Current FAQ Ground-Level Translators Digital Isolators GNDA to GNDB Difference 80V 3kVrms Galvanic Barrier No Yes GNDA to GNDB Leakage (VCC to GND…

  • [FAQ] How do I size my external RC components surrounding Auto-Bi Directional Translators to fit my System Requirements?

    Part Number: TXB0108 TXB0102 LSF0102 LSF0101 TXS0104E LSF0108 LSF0002 TXB0104 TXB0106 TXB0101 TXS0108E TXS0101 TXS0102 LSF0204 Tool/software: Auto Bi-Directional translators demand additional design considerations over other translators, such as external…

  • [FAQ]: My simulation in ICS is very slow - how do I fix it?

    FAQ: TPLD > Current FAQ The two biggest causes of slow simulation are: Fast oscillators and switching signals Large simulation timescales (simulations that take 1+ seconds) If the simulation is utilizing a square wave with a period that is…

  • [FAQ] Are TPLDs pin-to-pin compatible with competitor devices?

    FAQ: TPLD > Current FAQ Numerous TPLD products are either pin to pin or layout compatible with competing products. Our products utilize standard, JEDEC packaging standards.

  • [FAQ] Can my TPLD be changed after programming?

    FAQ: TPLD > Current FAQ Once a TPLD is permanently programmed or “burned” through OTP, the design cannot be changed. If you wish to change your design after permanently programming an OTP part, a new, previously unprogrammed part must be used.

  • [FAQ] How is TPLD programmed?

    FAQ: TPLD > Current FAQ TPLD is programmed through SPI communication enabled by the programmer firmware and InterConnect Studio (ICS). Each TPLD device uses 5 pins to program the device: 4 pins for SPI communication and 1 pin (GPI) that provides a specific…
