74LVC4245AD,112

Translators, Level Shifters Overview

The Nexperia 74LVC4245AD,112 is an octal dual supply translating transceiver featuring 3-state bus compatible outputs. It interfaces between a 3 V and 5 V bus in mixed supply environments. The device includes an output enable input (OE) and a direction control input (DIR). Supply voltage ranges are 1.5 V to 3.6 V for the 3 V bus (VCC(B)) and 1.5 V to 5.5 V for the 5 V bus (VCCA). Propagation delay is typically 10 ns at VCC(B)=2.7 V. Operating temperature spans -40 °C to +125 °C. Total power dissipation is 500 mW. Package: SOIC-24 (SOT137-1).

Translators, Level Shifters Feature Summary

• Dual supply architecture enabling translation between 3 V and 5 V logic levels.
• Schmitt-trigger inputs provide tolerance for slower rise and fall times.
• High-impedance state isolates buses when OE is HIGH or supplies are zero.
• Overvoltage tolerant control inputs up to 5.5 V.

Translators, Level Shifters Applications

• Interfacing between 3 V and 5 V buses in mixed supply environments.
• Bidirectional data transmission with direction control via DIR pin.
• Systems requiring high-impedance isolation of buses during suspend mode.

Translators, Level Shifters Procurement Notes

Verify package type SOT137-1 (SO24) matches design requirements. Confirm operating temperature range covers application extremes (-40 °C to +125 °C). Check supply voltage compatibility with system rails (1.5 V–5.5 V). Ensure OE and DIR pin configurations align with control logic. Validate power dissipation limits under maximum load conditions.

Translators, Level Shifters Selection Notes

Select this component for applications requiring bidirectional level shifting between 3 V and 5 V domains. Consider the SOIC-24 package for surface mount assembly. Evaluate propagation delay specifications against system timing constraints. Verify ESD protection levels meet environmental standards. Assess power consumption characteristics for low-power designs.

Translators, Level Shifters Part Context
