SN74AXC4T245QPWRQ1

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AXC4T245QPWRQ1 is an automotive-grade, four-bit dual-supply bus transceiver with voltage translation capabilities. It operates within a supply voltage range of 0.65 V to 3.6 V on both ports A and B. The device features a propagation delay of 4 ns and supports bidirectional data flow controlled by direction and output enable signals. It is housed in a TSSOP-20 package and meets AEC-Q100 qualification standards for automotive applications.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Dual-supply architecture enabling direct voltage level translation between different logic domains without external components.
• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
• High-speed performance with low propagation delay suitable for demanding data bus interfaces.

Buffers, Drivers, Receivers, Transceivers Applications

• Automotive infotainment systems requiring interface between varying voltage logic levels.
• Telematics control units connecting microcontrollers to peripheral devices.
• Body control modules managing communication across mixed-voltage sensor networks.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'Q1' confirms AEC-Q100 automotive qualification status. Confirm the 'PWR' suffix indicates the TSSOP-20 package type. Ensure the component matches the required voltage translation specifications for the target application. Check for RoHS compliance documentation if environmental regulations apply. Validate that the manufacturer source provides official datasheets for technical verification.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional translation between two independent power rails is required in space-constrained designs. The four-bit width suits narrower data buses where pin count must be minimized. Consider the 4 ns speed for high-frequency interfaces. Verify that the input voltage ranges align with the source logic family. Evaluate thermal performance within the specified operating temperature range.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to Texas Instruments' SN74AXC series, which focuses on advanced low-voltage translation solutions. It complements other bus transceivers like the SN74LVC8T245 but offers higher speed and lower voltage operation. The Q1 suffix denotes automotive grade, distinguishing it from standard commercial variants. It serves as a bridge for modern automotive electronics transitioning to lower voltage standards.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74AXC4T245DRLRQ1: Same functional specification in a smaller WSON package. SN74AVC4T245QPWRQ1: Similar function but with different electrical characteristics and speed profiles. Verify pin compatibility and voltage thresholds before substitution.
