SN74LVC2T45-Q1: Thermal Spec in EC table

Joey Christ

Part Number: SN74LVC2T45-Q1

Hello - please note the thermal differences in the 2 datasheet revisions below. Did the thermal characterization of this device change or is this a typo?

thanks - Joey

Michael - thanks for the help, but I want to verify my understanding of the situation. The link provided above, to another post, pertains to SN74LVC2T245, not SN74LVC2T245-Q1. Are you indicating that the BOM has changed for both devices and that there is a PCN for both devices?

thanks - Joey

Hi Joey,

Per our email, while the PCN referred to is for thermal, please note that the datasheet's electrical characteristics temp range will be updated and it is recommended to use the temperature under the datasheet’s operating free-air temp, thanks.

Best Regards,

Michael.
