Other Parts Discussed in Thread: SN74LVC3G17,
Hi,
Good Day. I have a customer who is working with SN74LVC3G14 and SN74LVC3G17. Please see below his query for your reference. Thank you very much.
I am currently troubleshooting an interface PCB that uses both SN74LVC3G14 and SN74LVC3G17 (driver and inverter). Both components are set up to function similar to a differential driver. The issue that we encounter is that at around +85°C, the output of the G14 begins to oscillate, and eventually outputs continuous voltage of VCC regardless of the input signal. The device receives TTL signal from a function generator at both inputs, and thus should see a TTL signal at the output. I checked the datasheets for both devices and the operating temperature is noted as -40°C and +125°C in open space. We are operating the device within the temperature spec.
Best Regards,
Ray Vincent
