74LVC2T45DC-Q100H
Overview
The 74LVC2T45DC-Q100H is an automotive-qualified (AEC-Q100) dual-bit, dual-supply voltage level translator designed for bidirectional communication between different logic voltage domains. It supports a wide range of supply voltages from 1.2V to 5.5V on both ports, enabling seamless interfacing between legacy 5V systems and modern low-voltage microcontrollers. The device features high-speed performance up to 420Mbps and high-impedance outputs when either supply is at ground.
Why Choose This Part
This translator features 420Mbps throughput and 24mA drive capability, making it suitable for high-speed data buses. It includes specialized Ioff circuitry for partial power-down modes and robust ESD protection exceeding 4000V HBM for automotive reliability. The dual-supply architecture allows VCCA and VCCB to be independent, providing maximum flexibility in multi-voltage system designs.
Applications
Key Specifications
Getting Started
Ensure that the DIR pin is tied to either VCCA or GND to set the data direction, and provide decoupling capacitors for both VCCA and VCCB rails. For evaluation, use a VSSOP8-to-DIP breakout board to integrate the device into a breadboard prototype for logic verification. Refer to the AEC-Q100 documentation for thermal and vibration considerations in automotive deployments.
