74AXP8T245BQJ

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AXP8T245BQJ is an 8-bit dual supply translating transceiver with 3-state outputs. It supports bidirectional level translation between any voltage nodes from 0.9 V to 5.5 V on both ports (VCC(A) and VCC(B)). The device features patented circuitry that prevents output glitches during power supply transitions ranging from 20 mV/µs to 5.5 V/s, eliminating the need for power supply sequencing. It includes IOFF circuitry for partial power-down applications and operates within a temperature range of -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Patented glitch-free circuitry ensures no output glitches occur during power supply transitions between 20 mV/µs and 5.5 V/s.
• Dual independent supply rails allow flexible voltage translation across the full 0.9 V to 5.5 V range without sequencing requirements.
• Integrated IOFF circuitry disables outputs to prevent damaging backflow current when the device is powered down.

Buffers, Drivers, Receivers, Transceivers Applications

• Bidirectional logic level shifting between mixed voltage systems
• Partial power-down mode operation in portable electronics
• Bus interface translation in low voltage embedded designs

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'J' against official Nexperia documentation to confirm tape and reel packaging specifications. Ensure the DHVQFN-24 package variant matches the required PCB footprint. Confirm AEC-Q100 qualification status if automotive compliance is mandatory for the application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when simultaneous bidirectional translation between widely varying voltage domains is required without complex sequencing logic. The wide input voltage tolerance up to 5.5 V allows direct interfacing with higher voltage buses even if one side is powered at lower voltages. Consider the low static power consumption for battery-operated systems requiring suspend modes.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AXP family of high-speed translating transceivers. Unlike standard bus transceivers, it is specifically engineered for dual-supply environments where voltage levels on either port can vary independently. It serves as a bridge for communication between subsystems operating at different logic levels.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for 74AXP8T245 variants with different package codes such as PW for TSSOP-24 if leaded options are needed. Verify pin compatibility before substituting with other 8-bit translators like the 74LVC8T245 series, noting differences in transition speed and glitch prevention features.
