General Description
Features
The MAX3394E/MAX3395E/MAX3396E bidirectional
level translators provide level shifting required for data
transfer in a multivoltage system. Internal slew-rate
enhancement circuitry features 10mA current-sink and
15mA current-source drivers to isolate capacitive loads
from lower current drivers. In open-drain systems, slew-
rate enhancement enables fast data rates with larger
pullup resistors and increased bus load capacitance.
