Overview

The NTS0104BQ is a 4-bit, dual-supply translating transceiver featuring auto-direction sensing that enables bidirectional voltage level translation. It supports data rates up to 50 Mbps while bridging logic levels between a 1.65 V to 3.6 V supply on the A port and a 2.3 V to 5.5 V supply on the B port. This device is particularly useful for interfacing low-voltage microcontrollers with higher-voltage peripherals without the need for a direction-control signal.

Why Choose This Part

The NTS0104BQ eliminates the need for a dedicated direction-control pin, simplifying PCB routing and reducing MCU pin count requirements. It features lOFF circuitry for partial power-down mode, which isolates the bus when the device is powered down to prevent damaging backflow current. Additionally, it integrates pull-up resistors, making it directly compatible with both push-pull and open-drain system architectures.

Applications

I2C/SMBus Level Shifting
Translating clock and data lines between 1.8V processors and 3.3V or 5V sensors in open-drain configurations.
UART Communication
Providing bidirectional level translation for TX/RX lines between asynchronous serial interfaces operating at different logic levels.
GPIO Voltage Bridging
Connecting general-purpose IOs between low-power FPGAs or SoCs and high-voltage legacy logic devices.
Mixed-Voltage SPI Bus
Interfacing SPI master and slave devices where VCC rails are mismatched, supporting speeds up to 50 Mbps.

Getting Started

To implement the NTS0104BQ, ensure VCCA is always less than or equal to VCCB and provide local decoupling capacitors for both supply pins. Connect the Output Enable (OE) pin to VCCA through a pull-down resistor to keep the outputs in a high-impedance state during power-up. No software configuration is required as the device automatically detects data direction based on the driven signal.
