SN74AVC8T245PW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC8T245PW is an 8-bit dual-supply bus transceiver from the Texas Instruments AVC logic series, designed for configurable voltage-level shifting. It operates with a supply voltage range of 1.2 V to 3.6 V on both ports and supports data rates up to 320 Mb/s. The device features 3-state outputs and is housed in a 24-pin TSSOP package. It functions within a temperature range of -40°C to +125°C, with a typical propagation delay of 2.5 ns.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports bidirectional asynchronous data communication between two independent power domains
• Configurable voltage-level shifting across dual supply rails
• Provides partial power-down protection via Ioff circuitry to prevent backflow current
• Includes VCC isolation to disable outputs if either supply voltage drops below 100 mV

Buffers, Drivers, Receivers, Transceivers Applications

• Voltage translation between low-voltage microprocessors and higher-voltage peripherals
• Bidirectional level shifting in embedded systems with mixed voltage nodes
• Data bus interfacing in industrial control applications requiring robust isolation

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements before integration. Confirm RoHS compliance status through manufacturer datasheets. Validate lead times directly with authorized distributors as availability fluctuates.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing devices operating at different voltage levels within the 1.2 V to 3.6 V range. Consider the 24-pin TSSOP package for surface-mount assembly constraints. Evaluate the 320 Mb/s data rate capability against system timing requirements. Verify thermal performance specifications for high-temperature environments up to 125°C.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AVC8T245 family of dual-supply bus transceivers. It shares functional similarities with other members like the SN74AVC8T245PWR but differs in packaging and reel configuration. The AVC series is optimized for low-voltage applications requiring flexible voltage translation capabilities.
