SN74AVC20T245DGGR Description

Short technical summary and product information.

The SN74AVC20T245DGGR 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 device is optimized for VCCA/VCCB settings between 1.4 V and 3.6 V but remains operational with supplies as low as 1.2 V.

 

Key features include overvoltage-tolerant inputs and outputs, enabling mixed-voltage-mode data communications. The transceiver supports partial-power-down mode operation via its Ioff feature. It offers high data rates, reaching up to 380 Mbps for 1.8-V to 3.3-V translation, and provides robust ESD protection exceeding JESD 22 standards.

 

Packaged in a 56-TSSOP, the SN74AVC20T245DGGR is suitable for surface mount applications. Its operating temperature range is -40°C to 85°C. The device is designed for applications requiring bidirectional data transfer between systems operating at different voltage levels.
