SN74LVC16T245DGVR

The SN74LVC16T245DGVR from Texas Instruments is a 16-bit, noninverting, dual-supply bus transceiver. It is designed for asynchronous communication between two data buses, offering configurable voltage translation capabilities. The device operates with dual power supply rails, allowing each port to function independently over the full 1.65-V to 5.5-V power supply range. This enables universal low-voltage bidirectional translation between common voltage nodes like 1.8-V, 2.5-V, 3.3-V, and 5-V.

Key features include overvoltage-tolerant inputs and outputs, supporting mixed-voltage-mode data communications. The control inputs (DIR and OE) are referenced to VCCA. The transceiver also incorporates a VCC isolation feature, ensuring both ports enter a high-impedance state if either VCC input is at GND. It supports partial power-down applications through its Ioff feature, which disables outputs to prevent damaging current backflow.

This transceiver is suitable for applications requiring flexible voltage level shifting and bidirectional data transfer. It is available in a 48-TVSOP package and operates within an industrial temperature range of -40°C to 85°C.
