SN74AVC4T774: Similar parts with more outputs

Part Number: SN74AVC4T774
Other Parts Discussed in Thread: TXU0104, TXU0204

Hello,

I am interested in the functionality of you SN74AVC4T774 level shifter. Specifically, this part has the capability of specifying the direction of each shift pair, for a total of 4 pairs. Does T.I. make a similar part with more pairs, perhaps 6 or 8 pairs?

Fundamentally I am shifting a SPI bus, but I also need to shift 2 other signal I/O lines.

Thank you,

-Ben

    The 774 is the only level shifter with individual direction controls. When you have more than four signals, you have to make do with an 8-channel device or to combine multiple devices. (The new TXU0104/TXU0204/TXZU0304 might be helpful.)
