Hi, I am using TXB0108 Voltage Level Translator for FPGA based DAQ unit. In datasheet, continious output current of the I/O pins of this level translator seems +/-50mA. I want to learn that by using which circuitry ,can I test this current ability is correct. Because, I need 24 mA output current from each channel and it seems i couldn't get this value.

Hi,

'+/-50 mA' is maximum value which measured at stress testing. In normal operation, the maximum current is less than 18mA during transition time. When at high-low state, the soure or sink current is less than 5 mA.

Thanks

Hi,

Thanks for explanation. According to this explanation, Which IC should i use to reach 24 mA output current for each channel and it should also be bi-directional.

Thanks.
