Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing 5 V logic interfaces requiring high drive strength and fast propagation speeds. Ensure the application environment remains within the specified -40 °C to +85 °C temperature range. Confirm that the system architecture accommodates the four independent output enable signals required to control the 3-state buffers effectively.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ABT series, which utilizes BiCMOS technology to deliver higher speed and drive capability compared to standard CMOS or LVC families. It is designed specifically for 5 V applications, distinguishing it from lower voltage logic families like LVC or AUP. The 16-bit configuration allows for efficient parallel data transmission in wide-bus architectures.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for the 74ABT16240ADL variant if an SSOP48 package is required instead of the TSSOP48 used by the ADGG suffix. Verify pinout compatibility before substitution.
