The MAX3394E/MAX3395E/MAX3396E bidirectional level translators are used for data transfer in a multivoltage system. They feature internal slew-rate enhancement circuitry with 10mA current-sink and 15mA current-source drivers to isolate capacitive loads from lower current drivers. The slew-rate enhancement enables fast data rates with larger pullup resistors and increased bus load capacitance in open-drain systems. The logic-high levels are set by externally applied voltages, VCC and VL. A logic-low signal on one I/O side appears as a logic-low signal on the opposite I/O side. Each I/O line is pulled up to VCC or VL by an internal pullup resistor, allowing the devices to be driven by push-pull or open-drain drivers. The MAX3394E/MAX3395E/MAX3396E have a tri-state output mode, thermal-shutdown protection, and ±15kV Human Body Model (HBM) ESD protection on the VCC side for external signal protection. They accept VCC voltages from +1.65V to +5.5V and VL voltages from +1.2V to VCC, making them suitable 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.
The MAX3394E, MAX3395E and MAX3396E are bidirectional level‑translator devices that provide voltage translation between low‑voltage ASIC/PLD logic and higher‑voltage systems. They feature internal slew‑rate enhancement, 10 mA sink and 15 mA source drivers, tri‑state output, thermal‑shutdown protection and +15 kV HBM ESD protection on the VCC side.
These translators operate over a –40 °C to +85 °C temperature range, accept VCC from +1.65 V to +5.5 V and VL from +1.2 V to VCC, and support up to 6 Mbps with push‑pull drivers or 1 Mbps with open‑drain drivers. They are offered in multiple packages, including 8‑pin TDFN, 9‑bump UCSP, 12‑pin TQFN and 20‑pin TQFN.
