Overview

The LXS0104ZMAEX is a 4-bit bidirectional voltage level translator designed for interfacing between different logic voltage domains without a direction-control signal. It supports a wide voltage range with VCCA from 1.65V to 3.6V and VCCB from 2.3V to 5.5V, making it ideal for connecting low-voltage microcontrollers to higher-voltage peripherals. This device features integrated 10 kOhm pull-up resistors and supports both push-pull and open-drain applications.

Why Choose This Part

The auto-direction sensing capability simplifies PCB routing and firmware by eliminating the need for a DIR control pin. It offers robust ESD protection and power-off protection, ensuring that the I/Os are high-impedance when either supply is at 0V. The ultra-compact 1.7mm x 2.0mm XQFN package is specifically designed for space-constrained mobile and portable applications.

Applications

I2C/SMBus Level Shifting
The integrated 10 kOhm pull-up resistors and open-drain support make it a drop-in solution for I2C and SMBus buses operating across different voltage rails.
MDIO Interface
Facilitates high-speed management data input/output communication between network processors and PHYs with mismatched I/O voltages.
General Purpose Logic Translation
Translates push-pull logic signals at speeds up to 24 Mbps for SPI, UART, or GPIO interfaces between 1.8V, 2.5V, 3.3V, and 5V systems.

Getting Started

To use this device, ensure that VCCA is always less than or equal to VCCB and connect the OE pin to GND via a pull-down resistor to ensure high-impedance state during power-up. Since the device includes internal 10 kOhm pull-ups, external resistors may not be required for I2C unless lower impedance is needed for high capacitive loads. Decouple both VCCA and VCCB pins with 0.1uF ceramic capacitors placed as close to the pins as possible.
