NTB0104GU12
Overview
The NTB0104GU12 is a 4-bit, dual-supply bidirectional voltage level translator featuring auto-direction sensing and 3-state outputs. It enables seamless data transfer between devices operating at different logic levels, supporting a wide range from 1.2V to 3.6V on the A-port and 1.65V to 5.5V on the B-port. The device is designed for high-speed operation up to 100Mbps and includes Ioff circuitry to support partial power-down modes by preventing damaging backflow current.
Why Choose This Part
The NTB0104 eliminates the need for a direction-control signal, reducing pin count and simplifying PCB routing. It offers excellent power efficiency with a typical standby current of 1uA and protects sensitive circuitry via built-in ESD protection and Ioff partial power-down isolation. Its extremely small XQFN12 package (1.7mm x 2.0mm) is ideal for space-constrained mobile and embedded designs.
Applications
Key Specifications
Getting Started
To implement this part, ensure VCCA is always less than or equal to VCCB and provide decoupling capacitors close to both supply pins. The Output Enable (OE) pin should be tied to GND through a pull-down resistor to ensure high-impedance state during power-up. For prototyping, look for XQFN-12 to DIP adapter boards or evaluation modules that support the NTB series footprint.
