SN74AVC4T245PWTG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC4T245PWTG4 is a 4-bit dual-supply bus transceiver with configurable voltage-level shifting and 3-state outputs. It operates within a supply voltage range of 1.2V to 3.6V on both VCCA and VCCB rails. The device supports maximum data rates up to 380Mbps for 1.8V to 3.3V translation. Propagation delay is typically 2.9ns at VCCA=1.8V. It features I/Os that are 4.6V tolerant and includes Ioff circuitry for partial power-down mode operation.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Fully configurable dual-rail design allows each port to operate over the full 1.2V to 3.6V power-supply range.
• I/Os are 4.6V tolerant, enabling interface with higher voltage nodes while maintaining low-voltage compatibility.
• Ioff supports partial power-down mode operation by disabling outputs to prevent damaging current backflow.
• Control inputs VIH/VIL levels are referenced to the VCCA voltage for consistent logic thresholding.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the package type matches the PW (TSSOP-16) designation in the part number. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure ESD handling precautions are followed during installation due to the sensitivity of CMOS input structures.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when asynchronous bidirectional communication between two data buses operating at different voltage levels is required. The device is suitable for applications needing universal low-voltage translation between 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V nodes. Consider the 4.6V I/O tolerance if interfacing with slightly higher voltage peripherals.
