Other Parts Discussed in Thread: SN74AVCH8T245
Hi,
Good Day.
Customer had a question regarding SN74AVCH2T245 and SN74AVCH8T245. He connect either input pins or output pins or one of these two ICs to a circuit board node which has a diode of another IC connected to it. They expect to draw 100uA from a current source and measure -1V across the diode. How do he make sure SN74AVCH2t245 or SN74AVCH8t245 does not affect the voltage measurement? Power them off? Will just setting OE to high logic level make sure these ICs are not driving the node he is trying to measure?
The bus-hold circuitry on the powered-up side always stays active.
Please advise. Thank you very much.
Best Regards,
Ray Vincent
