TXS0108E 8-Channel Bidirectional Logic Level Converter Module, 3.3V/5V, 3-Pack

TXS0108E Module This module employs the TXS0108E chip, an 8-bit non-inverting translator with two independent configurable power supplies. The A port is designed to track VCCA, which accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB, which accepts any supply voltage from 1.65 V to 5.5 V. This allows for bidirectional voltage translation between any of the following low-voltage supply nodes: 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V. When the Output Enable (OE) input is low, all outputs are in a high-impedance state. To ensure a high-impedance state during power-up or power-down, OE should be pulled down through a pull-down resistor. Product Specifications: 1.Chip Adopted: TXS0108E 2.High-speed Full-duplex 8-channel Level Translation Module 3.Provides Bidirectional Communication Capability 4.Port A supports 1.2 V to 3.6 V, and Port B supports 1.65 V to 5.5 V (with VCCA≤ VCCB). Product Applications: 1.Communication compatibility between 5V microcontrollers and 3.3V modules, as well as 3.3V microcontrollers and 5V modules. 2.Level translation for communication between microcontrollers and SD cards. 3.Level translation for communication between microcontrollers and I2C, SPI serial devices. Note: The OE enable IO is active high and should be connected to the IO port of the lower voltage side to ensure a high-impedance state during power-up or power-down.
