The SN74AVCH20T245VR from Texas Instruments is a 20-bit noninverting bus transceiver designed for flexible voltage translation. It utilizes two separate configurable power-supply rails, allowing each port to operate independently over the full 1.2-V to 3.6-V power-supply range. This enables seamless bidirectional translation between various voltage nodes including 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V.
Key electrical characteristics include a maximum data rate of 380 Mbps for 1.8-V to 3.3-V translation and a propagation delay of 5 ns. The device features overvoltage-tolerant inputs/outputs, supporting mixed-voltage-mode data communications. It also includes a VCC isolation feature, ensuring high-impedance states when either VCC input is at GND, and Ioff support for partial-power-down mode operation. The inputs are protected with bus hold, eliminating the need for external pullup/pulldown resistors.
This transceiver is available in a 56-TVSOP package, suitable for surface mount applications. The operating temperature range is -40°C to 85°C. ESD protection exceeds JESD 22 standards, including 8000-V for the Human-Body Model.

The maximum data rate is 380 Mbps when translating from 1.8V to 3.3V, and varies for other translation voltages (260 Mbps for <1.8V to 3.3V or to 2.5V, 210 Mbps to 1.8V, 120 Mbps to 1.5V, 100 Mbps to 1.2V).
The propagation delay is 5 ns.
The operating temperature range is -40°C to 85°C.
It supports input and output voltages from 1.2V to 3.6V. The I/O pins are tolerant up to 4.6V.
ESD protection exceeds 8000V Human-Body Model (A114-A), 200V Machine Model (A115-A), and 1000V Charged-Device Model (C101).
The package is 56-TVSOP (also specified as 56-TFSOP, 0.173" width, 4.40mm width), surface mount.
