DIO74LVC1T45W6-7
Overview
The 74LVC1T45W6-7 is a single-channel, bidirectional voltage level translator designed for interfacing logic between different voltage domains ranging from 1.65V to 5.5V. It utilizes two independent power supply rails (VCCA and VCCB) to allow flexible level shifting between low-voltage microcontrollers and higher-voltage peripherals or legacy systems. The device features a direction control input and a tri-state output configuration for efficient bus management.
Why Choose This Part
This translator supports a wide supply range from 1.65V to 5.5V on both rails, offering maximum flexibility for multi-voltage designs. It features 24mA drive strength and Ioff circuitry, which prevents damaging backflow current during partial power-down. The SOT-26 package provides a small footprint while maintaining ease of assembly for high-density PCB layouts.
Applications
Key Specifications
Getting Started
To implement this device, connect the reference voltage of the logic source to VCCA and the target logic voltage to VCCB. Ensure the DIR pin is driven to the appropriate logic level to set the data flow direction (A to B or B to A). Bypass capacitors should be placed close to both VCC pins to minimize noise during high-speed switching.
