Category: Datasheet/Specs
Product Number: MAX4564
The MAX4564 specifies that it can operate at voltage levels as low as +/-1.8V. But this range is well below VIH and VIL thresholds for CMOS-and-TTL-compatible digital inputs. In cases where digital signals are greater than the supply voltages, (1) can the device be safely operated, and (2) what are the VIL and VIH ranges in those cases?
Use case:
I'd like to power the MAX4564 with +/-2.5V supply and control the switch through the IN pin with a 0-to-3.3V digital signal. The datasheet suggests that this might be possible since the internal diodes will clamp the input voltage to V+ + 0.3V, and I need only limit the current to <20mA. Is that the case?
Any clarification would be most appreciated! Thanks!
