Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring robust octal data buffering with low-voltage compatibility. The SN74LVT245DW is suitable for systems operating strictly within the 2.7 V to 3.6 V power domain. Engineers should consider the SOIC-20 package dimensions for PCB layout constraints and verify thermal dissipation capabilities under maximum load conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

Buffers, Drivers, Receivers, Transceivers FAQ

What is the direction control mechanism for the SN74LVT245DW?

Data flow direction is determined by the DIR input pin. A high logic level on DIR directs data from port A to port B, while a low logic level reverses the flow from port B to port A.

How does the output enable function operate?

The OE (Output Enable) input controls the state of the outputs. When activated, the outputs are enabled for normal operation; when deactivated, the outputs enter a high-impedance state to isolate the bus.
