Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DBR' corresponds to the SSOP-24 tape and reel packaging format required for automated assembly processes. Confirm that the 2.7 V to 3.6 V supply voltage range aligns with the target system's power rails. Ensure compatibility with LVTTL logic levels for both inputs and outputs to prevent signal integrity issues during data transmission.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal transceiver with latching functionality is required for 3.3 V systems. The 2.5 ns propagation delay suits applications demanding moderate to high-speed data throughput. Consider the 24-SSOP package dimensions for PCB layout constraints. Verify that the 64 mA sink current meets the load requirements of the connected bus lines without exceeding thermal limits.
