SN74AXCH4T245PWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AXCH4T245PWR is a 4-bit dual-supply bus transceiver from the SN74AXCH4T245 series, manufactured by Texas Instruments. It operates with a supply voltage range of 650 mV to 3.6 V and features a propagation delay of 181 ns. The device is housed in a 16-TSSOP package, supports surface mount installation, and functions within an operating temperature range of -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Dual-supply architecture enabling voltage level translation between independent power rails
• Configurable control input levels referenced to the A port supply voltage
• Extended industrial temperature operation capability for robust performance

Buffers, Drivers, Receivers, Transceivers Applications

• Voltage level translation between low-voltage and higher-voltage logic domains
• Bidirectional data bus interfacing in embedded systems
• Portable equipment requiring low-power operation

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix PWR corresponds to the TSSOP-16 package and reel/cut tape packaging configuration. Confirm RoHS compliance status and ensure the extended temperature grade matches application requirements. Cross-reference the manufacturer part number against official Texas Instruments documentation to validate authenticity and current production status before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional translation is required between two distinct voltage domains with a minimum supply as low as 650 mV. The AXCH series offers specific electrical characteristics distinct from AVCH or AVC variants. Ensure the 181 ns propagation delay meets system timing constraints and that the 16-TSSOP footprint fits the PCB layout design.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74AXCH4T245 family of high-performance bus transceivers. It shares functional similarities with the SN74AVC4T245 but utilizes different internal technology to achieve its specified electrical parameters. The part is designed for applications requiring reliable data transfer across varying voltage levels in compact form factors.
