4-ch, 2-V to 5.5-V buffers with 3-state outputs

The SNx4AHC125 devices are quadruple

bus buffer gates 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.

To ensure the high-impedance state

during power up or power down, OE must be tied to

VCC through a pullup resistor; the minimum value of the resistor is

determined by the current-sinking capability of the driver.
