The 74AVCH4T245GU is a 2-bit translation transceiver from NXP's 74AVCH family. It operates from 0.8V to 3.6V on both supply rails, enabling bidirectional voltage level translation between different logic domains. With 3-State outputs and 12mA drive capability, it is housed in a compact 16-XFQFN package. Ideal for mixed-voltage systems in smartphones, IoT devices, and automotive electronics, it simplifies PCB design by replacing discrete level shifters.
- Dual-Supply Voltage Translation: Seamlessly shifts between 0.8V and 3.6V domains, supporting sub-1V to 3.3V levels.
- Bidirectional Operation: Handles data flow in both directions without external direction control complexity.
- High Drive Current (12mA): Suitable for driving LEDs, relays, or long traces.
- Compact 16-XFQFN Package: Saves board space in dense consumer electronics.
Mixed-Voltage PCB Interfacing
Translate between 1.8V and 3.3V domains in multi-voltage designs, eliminating the need for discrete level-shifter ICs.
Smartphone Application Processor to Peripheral
Connect a 1.2V application processor to 3.3V sensors or memory, with bidirectional data flow for I2C or SPI.
FPGA to ASIC Communication
Bridge different I/O bank voltages between an FPGA (1.5V) and ASIC (2.5V) in high-speed digital systems.
Battery-Powered Dual-Voltage Systems
In IoT devices with separate 0.9V and 3.3V rails, provide low-power translation with 12mA drive for LEDs or relays.
Hot-Swap Server Boards
3-State outputs allow bus isolation during hot-swapping of daughter cards in servers.
Automotive Infotainment
Translate between 1.8V MCU and 3.3V display interfaces, with -40°C to 85°C operation for cabin electronics.
