74LVTH245MTC

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74LVTH245MTC is an octal bidirectional transceiver featuring non-inverting buffers with three-state outputs. It operates within a voltage range of 2.7V to 3.6V and supports bus-oriented applications. The device includes bushold data inputs, eliminating the need for external pull-up resistors to hold unused inputs. It offers live insertion/extraction capability and power-up/down high impedance for glitch-free bus loading. Outputs provide source/sink currents of -32 mA/+64 mA. The component is housed in a TSSOP-20 package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix (e.g., MTC vs MTCX) against current manufacturer documentation to confirm packaging type, as availability may vary between tube and reel formats. Confirm RoHS compliance status through official datasheets or environmental files, as legacy stock may differ from current production runs. Ensure the supplier provides valid traceability documents for automotive or industrial grade requirements if applicable.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust bus holding capabilities without external pull-up resistors. It is suitable for applications needing live insertion support and protection against glitches during power transitions. Compare propagation delay and output drive strength against other LVTH series variants to ensure compatibility with target clock speeds and load capacitances in the specific circuit design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74LVTH logic family, characterized by low voltage operation and enhanced features like bushold inputs. It serves as a bidirectional buffer for transferring data between buses operating at different voltage levels or within the same low-voltage domain. The TSSOP-20 package allows for compact surface-mount assembly in space-constrained electronic designs.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct equivalents such as the MC74LVTH245MTC from ON Semiconductor, which shares identical pinouts and functional specifications. Verify that any substitute maintains the bushold feature and compatible output drive currents to ensure seamless integration into existing bus architectures.
