Overview

The 74AVCH1T45GW is a single-bit, dual-supply bidirectional voltage level translator capable of high-speed data rates up to 500Mbps. It operates across a wide voltage range from 0.8V to 3.6V on both supply rails, making it suitable for bridging legacy 3.3V logic with ultra-low voltage sub-1V domains. This device features a bus-hold function that maintains the last known logic state on the data inputs when the interface is not actively driven.

Why Choose This Part

This translator supports extremely high data rates of 500Mbps and features integrated bus-hold circuitry, which eliminates the need for external pull-up or pull-down resistors on CMOS inputs. It provides robust ESD protection with 8000V HBM and includes IOFF circuitry for partial power-down mode, preventing damaging backflow current when the device is powered off.

Applications

High-Speed Interface Bridging
Translating logic levels between high-performance FPGAs, ASICs, or processors operating at 0.8V and peripherals at 1.8V or 3.3V.
Mobile and Battery-Operated Devices
Used in power-sensitive designs to bridge low-voltage application processors with higher-voltage sensors or communication modules.
GPIO Level Shifting
Providing bidirectional signal translation for status flags, interrupt lines, or simple serial data lines in mixed-voltage systems.

Getting Started

To use this part, provide the logic reference voltage for each side to VCCA and VCCB, ensuring both are within the 0.8V to 3.6V range. Direction is controlled via the DIR pin; a high level typically translates from A to B, while a low level translates from B to A. For prototyping, this SOT-363 package requires a dedicated breakout board or a PCB with 0.65mm pitch footprints.
