TRS3253E receiver ouptut impedance when powered down
Anyone know what the state of the receiver outputs are when the TRS3253E is powered down? The datasheet says "Z" meaning high impedance of course, but doesn't specify what it actually is. I just want to be sure that I can use it on my bus without interfering with the relatively weak drives and long wires that the other components will be connected through.
Also, while I'm asking, there's a absolute maximum spec for the FORCEON and FORCEOFF pins of 6V.
However is would there be detremental effects if driving forceon and forceoff higher than VL and VCC? for example, if VL and VCC are 3.3V and FORCEON/FORCEOFF are being driven at 0 and 5V?
There is an Ioff spec in the datasheet. With this you can calculate the off impeadance.
Thanks Chris - that gives me a resistance that's more than high enough to avoid messing with the bus.
How about the other part of the question - can I drive the FORCEON and FORCEOFF pins with 5V logic if the VL is 2.5 or 3.3V?
