74LVX3245QSC

Translators, Level Shifters Overview

The Fairchild Semiconductor 74LVX3245QSC is an 8-bit dual-supply translating transceiver featuring three-state outputs. It facilitates bidirectional data transfer between a 3V bus and a 5V bus in mixed voltage environments. The device utilizes separate VCCA (2.7V to 3.6V) and VCCB (4.5V to 5.5V) power supplies. Control inputs OE and T/R are powered by VCCA, ensuring compatibility with low-voltage logic levels.

Translators, Level Shifters Feature Summary

• Provides true voltage translation between 3V and 5V buses through electrical isolation of A and B sides
• Features bidirectional interface capability controlled by Transmit/Receive input for directed data flow
• Incorporates proprietary EMI reduction circuitry to ensure simultaneous switching noise performance

Translators, Level Shifters Applications

• Interfacing 3.3V CPU systems with 5V peripheral components in notebook computers
• Mixed voltage system designs requiring reliable level shifting between different supply domains
• Bidirectional data transmission paths in embedded systems with heterogeneous voltage requirements

Translators, Level Shifters Procurement Notes

Verify the specific suffix QSC indicates qualified automotive or industrial grade status as per manufacturer documentation. Confirm package type corresponds to SOIC-24 specifications. Ensure sourcing channels provide original manufacturer traceability. Check RoHS compliance status against current regulatory standards before integration into final assemblies.

Translators, Level Shifters Selection Notes

Select this component when interfacing distinct voltage domains without relying on resistor dividers. The dual-supply architecture ensures clean VIH signals across both directions. Consider the 24mA output drive capability for moderate load conditions. Verify that control pins operate within the VCCA range to maintain proper direction and enable states.

Translators, Level Shifters Part Context

This part belongs to the LVX series of low-voltage CMOS devices designed for high-speed applications. It serves as a functional equivalent to the standard 74LS245 but operates at lower voltages. The family provides solutions for modern portable electronics where power efficiency and voltage compatibility are critical design constraints.

Translators, Level Shifters Replacement Considerations

The 74LVX3245WM is a documented variant within the same product line offering identical logical functionality. Verify pinout compatibility and package dimensions before substitution. Ensure replacement parts meet the same voltage and current specifications for seamless integration.
