SN74AVC8T245PWG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC8T245PWG4 is an 8-bit dual-supply bus transceiver from the Texas Instruments AVC logic series, housed in a 24-pin TSSOP package. It supports configurable voltage-level shifting between VCCA and VCCB rails ranging from 1.2V to 3.6V. The device features 3-state outputs with a maximum data rate of 320 Mb/s and a propagation delay of 2.5 ns. It operates within a temperature range of -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable voltage-level translation for bidirectional asynchronous data communication between different voltage domains
• Supports dual power supply rails allowing independent A and B port voltage configurations
• Integrated Ioff circuitry provides partial power-down protection to prevent current backflow

Buffers, Drivers, Receivers, Transceivers Applications

• Voltage level translation between low-voltage processors and higher-voltage peripheral buses
• Bidirectional data buffering in mixed-voltage system architectures
• High-speed interface isolation in industrial control systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and green manufacturing status as per Texas Instruments standards. Confirm the package type matches the required PCB footprint for surface-mount assembly. Ensure the operating temperature range meets the environmental requirements of the target application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing logic families requiring voltage translation between 1.2V and 3.6V rails. The 8-bit width suits parallel data buses. Consider the 2.5 ns propagation delay for timing-critical paths. Verify that the TSSOP-24 package fits the available board space constraints compared to alternative packages like RHLR.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AVC8T245 family of dual-supply bus transceivers designed for flexible voltage translation. It shares functional similarities with other AVC series devices but is distinct in its 8-bit configuration and TSSOP-24 packaging. It serves as a bridge for interoperability between diverse digital components operating at different supply voltages.
