Toshiba - 74AVC4T245FT: A High-Speed Voltage-Level Translating IC with Flexible 2-bit×2 Configuration

The 74AVC4T245FT is a high-efficiency CMOS 2-bit×2 bus transceiver that stands out for its flexible operation over a wide voltage range from 0.8 V to 3.6 V. This product enables bidirectional signal transmission between systems with different voltage levels without conflict or communication errors. Additionally, it supports independent power-up sequencing, making installation and operation easier in real-world environments.

With its intelligent bidirectional signal transmission capability controlled via the DIR pin, the A/B pins can be flexibly configured as either inputs or outputs, effectively supporting various system design requirements. The IC offers a fast response speed, with a propagation delay of just 3.6 ns, optimizing performance for high-speed applications such as digital data transmission.

Moreover, the 74AVC4T245FT delivers significant power savings by automatically entering a high-impedance state when power is not supplied. The device operates reliably over a wide temperature range from -40°C to +125°C, making it suitable for harsh environments such as industrial systems, automotive applications, IoT devices, and modern mobile equipment.
