• Provides three-state outputs for effective bus line management

Buffers, Drivers, Receivers, Transceivers Applications

• Connecting microprocessors to memory modules with differing I/O voltages
• Interfacing general-purpose input/output ports across mixed-voltage logic families
• Facilitating communication between low-power controllers and higher-voltage peripheral devices

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the LVCH logic family meets the system's speed requirements, as its propagation delay differs from standard LVC variants. Ensure the dual-supply architecture aligns with the target application's power domain design before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional translation between dissimilar voltage domains is necessary. The LVCH series offers distinct electrical characteristics compared to the LVC series; verify that the 23.8 ns propagation delay satisfies the timing constraints of the interface. This part is suitable for applications requiring robust signal integrity across varying supply conditions without requiring external level-shifting components.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LVCH8T245 family, designed specifically for dual-supply bus applications. It serves as a bridge between logic families operating at different voltage potentials. The TSSOP-24 package provides a compact solution for space-constrained designs while maintaining the electrical performance required for high-speed data transfer in mixed-voltage systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LVC8T245PWR: Offers similar functionality but utilizes LVC logic characteristics rather than LVCH. Verify if the propagation delay and drive strength differences impact the specific circuit timing requirements.
