Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type matches the required footprint, as the 74ABT125 series includes SOIC, SOP, and TSSOP variants. Confirm that the ordering suffix 'X' corresponds to tape and reel packaging if automated assembly is intended. Ensure the design accounts for the recommended operating conditions, specifically the 4.5V to 5.5V supply voltage range and the -40°C to +85°C ambient temperature limits.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad buffer with 3-STATE outputs and high drive capability is required. The ABT125 offers superior speed and current drive compared to standard logic families. Consider the specific package dimensions of the 14-Lead SOP variant for board layout constraints. Verify that the input edge rates meet the minimum requirements of 50mV/ns for data inputs and 20mV/ns for enable inputs to ensure proper switching performance.

Buffers, Drivers, Receivers, Transceivers Part Context

The 74ABT125 belongs to the ABT logic family, which utilizes BICMOS technology to provide high-speed operation with low power consumption.
