74LVXC3245WM

Translators, Level Shifters Overview

The 74LVXC3245WM is an 8-bit dual-supply configurable voltage interface transceiver with 3-STATE outputs. It operates with a VCCA supply of 2.7V to 3.6V and a flexible VCCB supply of 3.0V to 5.5V. The device features bidirectional data transfer between the A Port (dedicated 3V) and B Port (configurable). Outputs source or sink up to 24 mA. Propagation delays range from 1.0 ns to 9.5 ns depending on direction and load. Quiescent current is typically 5 µA at 25°C. Operating temperature spans -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Configurable voltage interface allowing B Port to track VCCB levels for seamless 3V to 5V bus translation
• Allows B Port I/O pins and VCCB to float simultaneously when Output Enable is HIGH, supporting hot insertion
• Implements proprietary EMI reduction circuitry to minimize simultaneous switching noise
• Control inputs compatible with TTL logic levels for robust interfacing

Translators, Level Shifters Applications

• PCMCIA and other real-time configurable I/O applications
• Low power notebook designs requiring dual supply translation
• Interfaces meeting ISA bus standard (IEEE P996) requirements

Translators, Level Shifters Procurement Notes

Verify the exact ordering code against the manufacturer's current database, as Fairchild part numbers may have been updated following integration into ON Semiconductor. Confirm package availability in SOIC-24 format. Ensure compliance with RoHS standards and check for any specific lifecycle status changes that may affect long-term supply continuity.

Translators, Level Shifters Selection Notes

Select this component when a bidirectional translator is required between a fixed 3V host system and a variable 3V-to-5V peripheral bus. The device is suitable for applications needing configurable I/O levels where the B Port must adapt to different card voltages. Ensure the design accommodates the recommended power-up sequencing to prevent bus contention during initialization.

Translators, Level Shifters Part Context

This device belongs to the LVXC series of low-voltage CMOS translating transceivers. Originally manufactured by Fairchild Semiconductor, it is now part of the ON Semiconductor portfolio. The component serves as a bridge for systems requiring voltage level shifting between different logic families while maintaining high-speed data integrity and low power consumption.

Translators, Level Shifters Replacement Considerations

Check for functional equivalents within the 74LVX or 74LVC series that support dual supplies. Verify pin compatibility and electrical characteristics such as output drive strength and propagation delay. Ensure any substitute supports the floating B Port feature if hot-swapping capability is required.
