† Component qualification in accordance with JEDEC and industry

standards to ensure reliable operation over an extended

temperature range. This includes, but is not limited to, Highly

Accelerated Stress Test (HAST) or biased 85/85, temperature

description/ordering information

The SN74AHCT125 is a quadruple bus buffer gate featuring independent line drivers with 3-state outputs. Each

output is disabled when the associated output-enable (OE) input is high. When OE is low, the respective gate

passes the data from the A input to its Y output.

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
