Texas Instruments TXS0108EPWR 8-Bit Level Translator, TSSOP-20

The Texas Instruments TXS0108EPWR is an advanced 8-bit bi-directional level-shifting voltage translator, designed for modern electronic systems requiring interface between different logic voltage levels. It is engineered for both open-drain and push-pull applications, offering a versatile solution without the need for a direction-control signal.

This non-inverting translator utilises two separate, configurable power-supply rails (VCCA and VCCB). The A port supports a voltage range from 1.4V to 3.6V, while the B port operates from 1.65V to 5.5V, with the condition that VCCA is less than or equal to VCCB. This flexibility makes it ideal for bridging communication between processors, sensors, memory, and peripherals in complex devices.

Key Performance Features

• High-Speed Data Transfer: Supports maximum data rates of 110 Mbps for push-pull configurations and 1.2 Mbps for open-drain applications when VCCA is 3.3V ±0.3V.
• Simplified Power Management: No power-supply sequencing is required, allowing either VCCA or VCCB to be ramped up first without risk to the device.
• Robust Design: Features a fast propagation delay of 4.8ns and a latch-up performance exceeding 100mA per JESD 78, Class II standards.
• Wide Operating Range: Reliable performance is guaranteed across a broad temperature spectrum from -40°C to +85°C.

Applications

This level translator is perfectly suited for a wide array of contemporary consumer and computing electronics, including handsets, smartphones, tablets, and desktop PCs. Its 20-pin TSSOP package offers a compact footprint for space-constrained PCB designs.

Important Handling Note: The device has limited built-in ESD protection. During storage or handling, leads should be shorted together or the device placed in conductive foam to prevent electrostatic damage to the MOS gates.
