Interfacing TNT4882 with 3.3 V MCU

[chunyu]

Dear Sir,

I am looking into using a TNT4882 chip to interface with GPIB Bus. Currently I have selected a MCU with Voh of 3.3 V. I would like to use a Xilinx 9536XL CPLD to interface with the TNT 4882. However, I have not been able to find the electrical Specification of the TNT4882 ASIC. There has been no mention of the logic level it supports. Please let me know how if this is possible. Thanks. Regards.

Hello,

Thanks for contacting National Instruments.

To address your questions regarding logic levels of the TNT 4882, take a look at the following Data Sheet for the chip. Page 12 of the manual addresses this logic level question as well as other specifications of the chip.
