Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit wide data paths between different voltage domains. Ensure the design accommodates the specified propagation delays and output drive capabilities. Consider the thermal environment as junction temperatures can impact reliability. Verify that the application does not exceed the absolute maximum ratings for input/output voltages and currents.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ALVT logic family, which combines the speed of ALVC with the 5V tolerance of LVTTL. It is manufactured by NXP Semiconductors (formerly Philips Semiconductors). The DGG suffix indicates a 48-pin Plastic TSSOP Type II package. This series is commonly used in embedded systems and industrial applications where robust data transmission across mixed-voltage buses is required.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible alternatives such as the SN74ALVT16245 from Texas Instruments or the 74AVC16245 from Nexperia. Ensure that any substitute matches the 48-pin TSSOP package and meets the same electrical specifications for voltage levels and drive strength.

Buffers, Drivers, Receivers, Transceivers FAQ

Does the 74ALVT16245 support live insertion?

Yes, the device permits live insertion and extraction, allowing it to be connected to a powered bus without causing current loading issues.

What is the purpose of the bus-hold inputs?

The bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs at a defined logic level, simplifying the circuit design.
