74AVC4T245BQ

The 74AVC4T245BQ is a high-performance, low-voltage, quad dual-supply translating transceiver from Nexperia. It is designed for asynchronous communication between data buses of different voltage levels, supporting translation between 1.2V to 3.6V on both sides. The device features four bidirectional buffers with separate input-output ports, allowing for direct interfacing between mixed voltage systems. Each channel can be independently configured for either direction, controlled by a direction pin (DIR) and an output enable pin (OE).
Key features include partial power-down protection, ensuring the device does not drive the bus when powered down, contributing to low power consumption. The 74AVC4T245BQ also operates with low dynamic power dissipation, making it suitable for battery-powered applications. Its high-speed operation supports data rates up to 380 Mbps (at 1.8V to 3.3V translation) and ensures proper signal integrity with its balanced drive capability. The device is housed in a compact TSSOP or HVQFN package, optimizing space for dense circuit board designs, and is widely used in applications like mobile devices, computing, and consumer electronics.

The 74AVC4T245BQ is a 20-pin IC used for voltage translation, specifically designed for asynchronous bidirectional communication. It serves as a dual-supply bus transceiver with configurable voltage levels, supporting voltage translation between 1.2V to 3.6V. Each of its four bus transceiver channels is capable of translating signals in both directions, making it versatile for interfacing different voltage levels in digital circuits.
The pinout includes:
- VCCA and VCCB (Power Supply Pins): These supply power for two separate voltage domains.
- An (A1 to A4) and Bn (B1 to B4) (Data Pins): These are the input/output data pins for channels 1 to 4, allowing bidirectional data flow between two different voltage nodes.
- OE (Output Enable): This pin is used to enable or disable the outputs, providing control over the active state of the transceiver.
- GND (Ground): Common ground reference for the device.
This IC is particularly useful in applications requiring level shifting between low-voltage microcontrollers and higher-voltage peripherals, ensuring reliable communication without damaging components.
