I am looking at using an ADG3308 for level translation between 5 and 3.3 V on a SPI interface between a microcontroller (5 V) and a MEMS accelerometer (3.3 V).
I notice that in the Theory of Operation, Input Driving Requirements section (top of second column, page 16 in Rev. E datasheet), it states:
To ensure correct operation of the ADG3308/ADG3308-1, the circuit that drives the input of the device should be able to ensure rise/fall times of less than 3 ns when driving a load consisting of a 6 kΩ resistor in parallel with the input capacitance of the ADG3308/ADG3308-1 channel.
I assume the low rise time is required to trigger the one-shot generator correctly.
The microcontroller I am using gives it's I/O port rise time as 10-25 ns, which seems to comparable to other MCUs I have looked at. Does this mean the ADG3308 will not work in my application? If so, is there an alternative part which can handle slower rise times?
Thanks in advance,
