Hello,
My customer uses the SN74AVC24T245.
He uses the device to translate a signal from CPU(1.8V) to SoC(3.3V).
It is occurred a strange function at one of a channel that drive a LED.
I attach the file of timing chart and block diagram.
After the CPU initialize time, right operation B-port is Low, but B-port
is High level actually.
The A-port voltage is less than 150mV, there is no noize.
But when he uses a pull-down at A-port by 10kohrm, it is a normal operation.
A strange function occur using another channel or another sample.
Could you tell me the cause of the strange function?
Is it too long CPU initialize time?
Regards,
Naoki Aoyama
