U74HCT125

DESCRIPTION 

The U74HCT125 is a quadruple bus buffer gates with 3-state 

output. When OE is high, the Y outputs are in a high-impedance 

state. When OE is low, the device passes noninverted data from the 

A input to the Y output. 

To ensure the high-impedance state during power up or power 

down, OE should be tied to VCC through a pull-up resistor; the 

minimum value of the resistor is determined by the current-sinking 

capability of the driver. 

FEATURES 

* TTL-Voltage Compatible 

* Max tPD of 12 ns from A to Y at 5.5 V, CL = 50 pF 

* Low power consumption, ICC = 8μA (Max) at 5.5V 

* ±6mA output driver at 5V
