Overview
The TXS0104EDR is a 4-bit bidirectional voltage-level translator produced by Texas Instruments. This device is designed for use in both open-drain and push-pull applications, making it versatile for various electronic systems. It features two separate configurable power-supply rails, allowing for low-voltage bidirectional translation between different voltage nodes such as 1.8 V, 2.5 V, 3.3 V, and 5 V.
The device operates without the need for a direction-control signal and supports maximum data rates of 24 Mbps for push-pull configurations and 2 Mbps for open-drain configurations. It is available in a SOIC (D) package with 14 pins and operates over a temperature range of -40°C to 85°C.
