LSF0204: LSF0204QPWRQ1

Hi Rajan,

No, the LSF family of translators won't work with pull-down resistors. This is true for all of our auto-bidirectional voltage translators.

It's my understanding that JTAG is a unidirectional protocol -- can you use a device like SN74AXC4T774?

There's an application report that mentions this on page 9 here: Low Voltage Translation for SPI, UART, RGMII, JTAG Interfaces (Rev. B)
