Part Number: PCA9539
Other Parts Discussed in Thread: TCAL9539,

Hi team,

My customer designs Outdoor AP application. And their ambient temperature will be up to 95'C at least.

So do we have similar function solution with higher TA specification? Please suggest.

Thanks

    Hi Paul,

    TCAL9539 is a direct p2p compatible replacement and upgrade to the PCA9539. TCAL9539 includes higher temperature range, lower supply voltage, and agile IO p-port capability. 

    For TI's transceivers, our device portfolio follows the naming convention:

    PCA

    TCA

    TCAL

    With PCA being our older devices, and TCAL being our new and upgraded parts. A PCA device with the same number as a TCAL device is a p2p compatible replacement. For example PCA9539 to TCAL9539. 

    Regards,

    Tyler
