SN74AVCH4T245PWE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVCH4T245PWE4 is a 4-bit dual-supply bus transceiver from the Texas Instruments AVC logic family. It facilitates bidirectional data transmission between two independent buses operating at different voltage levels, supporting ranges from 1.2 V to 3.6 V. The device features a common control pin for direction selection and an active-low output enable function. Packaged in a TSSOP-16 surface-mount format, it offers a data rate of 380 Mb/s and a propagation delay of 2.9 ns. It operates within a temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports bidirectional translation between independent power domains with separate supply rails for Port A and Port B
• Provides high-speed data transfer capabilities suitable for demanding digital interfaces
• Features configurable direction control and active-low output enable functionality

Buffers, Drivers, Receivers, Transceivers Applications

• Mobile applications requiring low-voltage operation
• Consumer electronics utilizing mixed voltage logic levels
• Industrial control systems interfacing disparate voltage domains

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix E4 confirms RoHS compliance and lead-free status as per manufacturer specifications. Confirm the package designation matches the required TSSOP-16 footprint for PCB layout compatibility. Ensure the ordering part number aligns exactly with the requested tube packaging configuration rather than tape-and-reel variants.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits that require level shifting between 1.2 V and 3.6 V domains. The AVC series is appropriate for applications needing higher speed than standard HC logic while maintaining low power consumption. Verify that the 3-state outputs meet the bus driving requirements and that the single-direction control pin simplifies the interface logic design.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74AVC4T245 family of dual-supply bus transceivers. It shares functional similarities with other members like the SN74AVC4T245PW but differs in specific manufacturing revisions or environmental certifications indicated by the suffix. It serves as a bridge for communication between components powered by different voltage supplies.
