74LVXC4245QSCX

Translators, Level Shifters Overview

The Fairchild Semiconductor 74LVXC4245QSCX is an octal dual-supply configurable voltage interface transceiver housed in a 24-pin TSSOP package. It provides bidirectional data translation between two independent buses operating at different voltage levels, typically 3.3V and 5V. The device features three-state outputs and allows for flexible configuration of the B-port I/O pins to match the VCCB supply voltage range. Designed for asynchronous communication, it ensures signal integrity through controlled switching speeds and low noise characteristics suitable for high-speed digital interfaces.

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'QSCX' against official Fairchild or onsemi documentation to confirm exact packaging and tape-and-reel specifications. Ensure the component meets RoHS3 compliance requirements if mandated by your design standards. Cross-reference the manufacturer part number with current distributor listings to confirm availability status, as legacy logic families may have limited stock or end-of-life implications.

Translators, Level Shifters Selection Notes

Select this component when designing systems that require robust voltage translation between 3.3V and 5V buses without altering the PCB layout. It is suitable for applications needing high noise immunity and low power dissipation. Consider the 24-TSSOP package constraints regarding thermal performance and pin pitch compatibility with your assembly process. Verify that the input logic levels are compatible with TTL standards as specified in the datasheet.

Translators, Level Shifters Part Context

This device belongs to the 74LVXC series of low-voltage CMOS logic components. It is functionally compatible with standard 74-series 245 transceivers but offers enhanced performance in lower voltage environments. The LVXC family is characterized by its ability to handle wide voltage ranges while maintaining low power consumption. This specific model represents a specialized variant within the broader octal bus transceiver category.

Translators, Level Shifters Replacement Considerations

Public confirmed substitute part numbers include SN74LVCC4245ADWR from Texas Instruments. Verify pinout compatibility and electrical parameters before substitution. Other equivalents may exist within the 74LVC or 74LVXC families from different manufacturers, provided they support dual-supply operation and similar package dimensions.
