74AXP4T245BQX

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AXP4T245BQX is a 4-bit dual supply translating transceiver with 3-state outputs, housed in a DHVQFN16 package (SOT763-1). It supports bidirectional level translation between VCC(A) and VCC(B), both ranging from 0.9 V to 5.5 V. The device features low input capacitance of 1.2 pF and low output capacitance of 3.6 pF. Propagation delay ranges from 1.2 ns to 40 ns depending on voltage conditions. It operates within an ambient temperature range of -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Patented circuitry prevents output glitches during power supply transitions without requiring sequencing.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent damaging backflow current.
• Inputs accept voltages up to the maximum VCCO limit, providing high noise immunity.

Buffers, Drivers, Receivers, Transceivers Applications

• Bidirectional logic level translation between mixed voltage nodes
• Partial power-down applications requiring isolation
• Unidirectional logic level-shifting circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the ordering suffix 'X' corresponds to the specific reel packaging configuration required for your assembly line. Confirm that the DHVQFN16 thermal pad soldering requirements align with your PCB design guidelines. Ensure the component meets all relevant RoHS and REACH compliance standards for your target market regulations.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing systems operating at different voltage levels between 0.9 V and 5.5 V. It is suitable for designs requiring glitch-free power-up/down sequences and partial power-down capabilities. Consider the DHVQFN16 package for space-constrained PCB layouts needing thermal enhancement.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AXP series of translating transceivers. It shares functional similarities with other 74AXP variants but differs in package type and channel configuration. The BQ suffix indicates the DHVQFN16 leadless package, distinguishing it from TSSOP or SOIC versions.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible substitutes within the 74AXP family, such as the 74AXP4T245PWJ, if a different package is needed. Verify electrical parameters match exactly before substitution.
