U74AUC125 Datasheet
  

QUADRUPLE BUS BUFFER GATE WITH 3-STATE OUTPUTS

 

 

DESCRIPTION

 

The U74AUC125 device is designed for 0.8V to 2.7V VCC

operation, but is designed specifically for 1.6V to 1.95V VCC operation.

This device contains four independent line drivers with 3-state

outputs. Each output is disabled when the associated output-enable

input is high. To ensure the high-impedance state during power up or

power down, OE should be tied to VCC through a pullup resistor; the

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

capability of the driver.

This device is fully specified for partial-power-down applications

using IOFF. The IOFF circuitry disables the outputs, preventing damaging

current backflow through the device when it is powered down.

 

FEATURES

 

* Optimized for 1.8-V Operation and Is 3.6-V I/O Tolerant to Support

Mixed-Mode Signal Operation

* IOFF supports live insertion, partial-power-down mode, back-drive

protection

* Inputs accept voltages up to 2.7V

* Max tpd of 2.1ns at 1.8V

* Low static power consumption; ICC=±10μA (Max.)

* ± 8mA Output Drive at 1.8V
