74LVC4245AD-Q100J

Translators, Level Shifters Overview

The Nexperia 74LVC4245AD-Q100J 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, utilizing separate VCCA (1.5 V to 5.5 V) and VCCB (1.5 V to 3.6 V) power rails. The device includes OE and DIR control inputs for direction management and high-impedance isolation. It operates from -40 °C to +125 °C, complies with AEC-Q100 Grade 1 standards, and provides Schmitt-trigger input tolerance.

Translators, Level Shifters Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Octal bidirectional data translation between independent 3 V and 5 V logic domains
• High-impedance output state isolates buses when the OE pin is asserted HIGH
• Schmitt-trigger action at all inputs ensures tolerance for slow signal transitions

Translators, Level Shifters Applications

• Interfacing 3.3 V microcontrollers with 5 V automotive sensors
• Bidirectional voltage level shifting in mixed-voltage automotive networks
• Engine control unit (ECU) communication gateways

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'J' against the manufacturer's current ordering information to confirm package type and tape-and-reel specifications. Confirm that the SOIC-24 package variant remains active, as revision history indicates previous package types may have been removed or superseded by newer versions like TSSOP24 or DHVQFN24.

Translators, Level Shifters Selection Notes

Select this component when designing systems requiring robust voltage translation between 1.5 V and 5.5 V domains under automotive conditions. Ensure the application utilizes separate power supplies for ports A and B to enable proper level shifting. Verify that the required propagation delay and ESD protection levels meet the system's electrical constraints.

Translators, Level Shifters Part Context

This part belongs to the Nexperia 74LVC4245A-Q100 family of octal translating transceivers designed for automotive electronics. While the datasheet lists TSSOP24 and DHVQFN24 packages, the AD suffix denotes the SOIC-24 variant. This family supports wide supply ranges and offers high reliability for harsh automotive environments.

Translators, Level Shifters Replacement Considerations

The 74LVC4245APW-Q100J (TSSOP24) and 74LVC4245ABQ-Q100J (DHVQFN24) are direct functional equivalents within the same product family. These alternatives share identical electrical characteristics but differ in physical package dimensions and pinout compatibility.
