The ’BCT125A bus buffers feature independent line drivers with 3-state outputs. Each output is disabled when the associated output-enable (OE) 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.

  • Operating Voltage Range of 4.5 V to 5.5 V
  • State-of-the-Art BiCMOS Design Significantly Reduces ICCZ
  • 3-State Outputs Drive Bus Lines or Buffer
  • Memory Address Registers
