Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DWR' corresponds to the SOIC package and tape-and-reel carrier configuration. Confirm RoHS compliance status and lead finish specifications against current manufacturer documentation. Ensure the operating temperature range meets the application requirements before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring octal buffering within the 1.65 V to 3.6 V logic family. Consider the 2.8 ns maximum propagation delay for timing-critical paths. Evaluate the ±24 mA drive strength against load requirements. Verify pin compatibility if replacing legacy devices in existing layouts.

Buffers, Drivers, Receivers, Transceivers FAQ

How are the outputs controlled?

The device has two separate output-enable (OE) inputs. When OE is low, data passes from A inputs to Y outputs. When OE is high, the outputs enter a high-impedance state.

What is the recommended handling during power-up?

To ensure the high-impedance state during power-up or power-down, the OE input should be tied to VCC through a pullup resistor.
