Hi,
What is the best way to handle unused channels in a tristate buffer (a 74act125d to be exact) ground both input and control or don't worry about it? I was trying to determine which would cause the lowest power consumption but can't seem to work it out from the datasheet. There is mention of ΔIcct being 1.5ma per input, but I'm not sure I'm interpreting that correctly, are they saying that each channel adds 1.5ma to the current on VCC when tristated?
Also, is anyone aware of a buffer with the same specs but in a single channel? I keep coming up with ones that are active when control is high, but the above part number is active low.
Thanks.
