74AVCH4T245D,112

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AVCH4T245D,112 is a 4-bit dual supply translating transceiver with configurable voltage translation and 3-state outputs. It operates within a supply voltage range of 0.8 V to 3.6 V for both VCC(A) and VCC(B). The device supports maximum data rates up to 380 Mbit/s depending on the voltage translation configuration. It features IOFF circuitry for partial power-down applications and active bus hold circuitry to maintain valid logic levels on floating inputs.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Bidirectional level translation between low voltage nodes
• IOFF circuitry prevents damaging backflow current during power-down
• Active bus hold maintains valid logic levels on unused inputs
• Suspend mode isolates buses when one supply is at GND

Buffers, Drivers, Receivers, Transceivers Applications

• Partial power-down system designs
• Mixed voltage signal interfacing
• Bidirectional data bus translation

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm that the SO16 plastic small outline package variant aligns with PCB layout constraints. Ensure compliance with JEDEC standards relevant to the target application environment before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring bidirectional translation between any low voltage nodes ranging from 0.8 V to 3.6 V. Consider the SO16 package for standard surface mount requirements. Evaluate the need for suspend mode and IOFF functionality if partial power-down capabilities are essential for the system design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AVCH series of translating transceivers. It provides four bits of bidirectional data transfer capability. The device integrates direction control and output enable inputs to manage data flow effectively across different voltage domains without requiring external components for input stabilization.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for 74AVCH4T245GU or 74AVCH4T245BQ if alternative packages like XQFN16 or DHVQFN16 are needed. Verify functional compatibility with other 4-bit dual supply translators in the same family.
