SN74BCT760 IOL Distribution

Other Parts Discussed in Thread: SN74BCT760

All,

I have three questions regarding the output current ability of the SN74BCT760:

1) The datasheet notes the IOL Low-Level Output current as 64mA.  Is this 64mA per channel, or 64mA cumulatively across all channels?

2) If only one channel is in use, what is the maximum and range of current that the channel can source?

3) If all channels are in use, what is the range of output current available?

Thanks for your support --

    Each output is guarranteed to drive 64ma.  This is not the max it can drive it is the max it will drive into a specific load and still meet spec. These are tested per channel.

    The drive will not change with number of channels but keep in mind that if driving all channels the part will draw a lot of current and heat up.
