SN74AXC8T245PWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AXC8T245PWR is an 8-bit dual-supply bus transceiver from Texas Instruments, designed for bidirectional voltage level translation between different logic families. It operates with supply voltages ranging from 0.65 V to 3.6 V on both ports. The device supports data rates up to 380 Mb/s when both supplies are at least 1.8 V. It features a TSSOP-24 package and includes Ioff partial power-down protection to prevent current backflow during power-off states.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports bidirectional asynchronous data communication between A and B buses via configurable direction control pins.
• Provides VCC isolation functionality that disables all outputs and enters a high-impedance state if either supply voltage drops below 100 mV.
• Includes Ioff circuitry to disable outputs when the device is powered down, preventing damage from current backflow.

Buffers, Drivers, Receivers, Transceivers Applications

• Voltage level matching between devices operating at different voltage nodes such as 0.7 V, 0.8 V, 0.9 V, 1.8 V, 2.5 V, and 3.3 V.
• Bidirectional voltage shifting in communication interfaces requiring dual-supply operation.
• Industrial and automotive electronic systems utilizing mixed-voltage logic components.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix PWR indicates tape-and-reel packaging configuration distinct from tube variants like PW. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design accounts for the specified ESD protection levels and latch-up performance characteristics defined in the datasheet.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing low-voltage logic (down to 0.65 V) with standard 1.8 V or 3.3 V systems requiring high-speed translation up to 380 Mbps. Consider the TSSOP-24 package constraints and thermal dissipation requirements for -40°C to +125°C operational environments compared to alternative series like AVC or LVC.
