Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'MX' against official Fairchild documentation to confirm tape-and-reel packaging compliance. Ensure the component matches the 74ALVCH series specifications rather than standard ALS or HC variants. Confirm RoHS status and lead-free finish details directly from the manufacturer's datasheet before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring bidirectional data transfer between 3.3 V logic domains. It serves as a direct replacement for older 74ALS245 devices where lower voltage operation and reduced power consumption are required. Ensure the application does not require level shifting to voltages below 2.5 V.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Fairchild 74ALVCH family of advanced low-voltage CMOS logic devices. It shares functional similarities with the 74ALS245 but operates at lower supply voltages. The device is manufactured using silicon-gate CMOS technology, offering improved speed and power characteristics compared to legacy TTL-based counterparts.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The DM74ALS245AWMX is a compatible alternative within the same package, though it requires a higher supply voltage. For low-voltage applications, verify compatibility with other 74ALVCH series variants.
