MC74LVXC3245DTG

Translators, Level Shifters Overview

The MC74LVXC3245DTG is a configurable dual-supply octal transceiver with three-state outputs designed for 3 V systems. It features a dedicated 3.0 V A port and a B port that tracks the VCCB supply level, which ranges from 3.0 V to 5.0 V. The device supports bidirectional data flow between the ports, controlled by Transmit/Receive (T/R) and Output Enable (OE) inputs. It allows the B port and VCCB pin to float simultaneously when OE is high, facilitating hot-swapping applications.

Translators, Level Shifters Feature Summary

• Configurable dual-supply architecture enabling interface between fixed 3.0 V buses and variable 3.0 V to 5.0 V buses
• Simultaneous floating capability for the B port and VCCB pin when output enable is inactive
• Control inputs compatible with TTL voltage levels
• Outputs capable of sourcing and sinking up to 24 mA

Translators, Level Shifters Applications

• PCMCIA configurable I/O applications
• Real-time configurable input/output interfaces
• ISA bus standard compliance for notebook designs

Translators, Level Shifters Procurement Notes

Verify the specific package suffix 'DT' corresponds to the TSSOP-24 configuration required for your board layout. Confirm the presence of the 'G' suffix if lead-free certification is mandatory for your assembly process. Ensure the operating temperature range aligns with your system's thermal environment specifications before finalizing procurement.

Translators, Level Shifters Selection Notes

Select this component when interfacing a fixed 3.0 V host system with peripheral cards operating at either 3.0 V or 5.0 V. The device is suitable for designs requiring rail-to-rail output swings on the card side to maximize interface reliability. Consider its low quiescent power consumption for battery-operated portable electronics where power efficiency is critical.

Translators, Level Shifters Part Context

This part belongs to the LVXC logic family, characterized by low-voltage CMOS technology optimized for 3.3 V systems. It is functionally compatible with the standard 74 Series 245 octal transceivers but offers enhanced flexibility through its dual-supply design. The device is manufactured by onsemi and is available in both SOIC and TSSOP packages.

Translators, Level Shifters Replacement Considerations

Functionally equivalent parts include other octal bus transceivers with similar voltage translation capabilities. Verify pinout compatibility and electrical characteristics against alternative suppliers' offerings to ensure seamless integration without redesigning the surrounding circuitry.
