概要

Description

TXB0302DQMR is a high-speed bi-directional level shifter designed for interfacing between different voltage levels in digital circuits. It is particularly useful for systems that require communication between devices operating at different voltages, such as a 1.8V logic level microcontroller and a 5V peripheral. The device supports a wide range of voltage levels (from 1.2V to 5.5V) and can handle data rates up to 80 Mbps, making it suitable for high-speed applications.
The TXB0302DQMR features eight channels for data transfer, allowing simultaneous bi-directional communication. It employs a simple, low-power design, which enables easy integration into various electronic systems without extensive additional circuitry. The device is encapsulated in a compact package, facilitating space-efficient designs. Overall, the TXB0302DQMR is an essential component for designers needing reliable level shifting in mixed-voltage environments.

Features

The TXB0302DQMR is a bidirectional level shifting device designed for interfacing between different voltage levels in digital circuits, typically between 1.8V and 5V systems. Key features include:
1. Bidirectional Operation: Supports signal flow in both directions without the need for a direction control pin.
2. Multiple Channels: Typically has 4 channels, allowing simultaneous level shifting for multiple signals.
3. Wide Voltage Range: Operates over a broad voltage range (1.2V to 5.5V) for both high and low sides.
4. Fast Data Rates: Capable of handling data rates up to 100 Mbps, suitable for high-speed applications.
5. Low Power Consumption: Efficient design that minimizes power usage during operation.
6. Compact Package: Offered in a small footprint (SOT-23) for space-constrained applications.
This IC is ideal for applications in mixed-voltage systems, such as interfacing microcontrollers, sensors, and other digital devices.

Package

The TXB0302DQMR is available in a 48-pin VQFN (Very Thin Quad Flat No-lead) package. This compact and thermally efficient package design is suitable for various applications requiring level shifting and bidirectional voltage translation.

Pinout

The TXB0302DQMR is a bi-directional level shifter designed for translating logic levels between two different voltage domains. It features a total of 8 pins.
