MAX3394E/MAX3395E/MAX3396E
General Description
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, slewrate enhancement enables fast data rates with larger
pullup resistors and increased bus load capacitance.
Externally applied voltages, VCC and VL, set the logichigh levels for the device. A logic-low signal on one I/O
side of the device appears as a logic-low signal on the
opposite I/O side, and vice-versa. Each I/O line is
pulled up to VCC or VL by an internal pullup resistor,
allowing the devices to be driven by either push-pull or
open-drain drivers.
The MAX3394E/MAX3395E/MAX3396E feature a tristate output mode, thermal-shutdown protection, and
±15kV Human Body Model (HBM) ESD protection on
the VCC side for greater protection in applications that
route signals externally.
The MAX3394E/MAX3395E/MAX3396E accept VCC voltages from +1.65V to +5.5V, and VL voltages from +1.2V
to VCC, making them ideal for data transfer between low
voltage ASIC/PLDs and higher voltage systems. The
MAX3394E/MAX3395E/MAX3396E operate at a guaranteed data rate of 6Mbps with push-pull drivers and
1Mbps with open-drain drivers.
The MAX3394E is a dual-level translator available in
9-bump UCSP™ and 8-pin 3mm x 3mm TDFN packages.
The MAX3395E is a quad-level translator available in 12bump UCSP, and 12-pin 4mm x 4mm TQFN packages.
The MAX3396E is an octal-level translator available in 20bump UCSP and 20-pin 5mm x 5mm TQFN packages.
The MAX3394E/MAX3395E/MAX3396E operate over the
extended -40°C to +85°C temperature range.
