Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type SSOP20 (SOT339-1) matches the design requirements. Confirm the temperature range is -40°C to +85°C. Ensure the 5V logic level compatibility aligns with the system voltage. Check for RoHS compliance status if required by environmental regulations. Validate pinout against the schematic to avoid connection errors.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when driving long bus lines requiring controlled impedance and reduced signal reflection. The integrated series resistance eliminates external components for termination. Suitable for applications needing high-speed data transfer with minimal propagation delay. Consider the dual enable feature for flexible bus management. Ensure the operating voltage remains within the 4.5V to 5.5V range for optimal performance.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT series of high-performance BiCMOS logic devices. It is designed for applications demanding low static and dynamic power dissipation alongside high speed. The octal configuration provides eight buffered outputs, making it efficient for wide data buses. The 3-State capability allows multiple devices to share a common bus without interference.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct replacements within the 74ABT family that offer identical pinouts and electrical characteristics. Verify if newer revisions of the datasheet specify any changes in recommended operating conditions. Ensure any substitute maintains the 30-ohm internal termination resistor feature. Confirm package dimensions match the existing PCB footprint.
