SN74HC126PW .

The SN74HC126PW is a quadruple Bus Buffer Gate features independent line drivers with 3-state outputs. Each output is disabled when the associated output-enable (OE) input is low. To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pull-up resistor and the minimum value of the resistor is determined by the current-sourcing capability of the driver.

• High-current 3-state outputs interface directly with system bus or can drive up to 15 LSTTL loads
• 80µA maximum ICC low power consumption
• 11ns typical Propagation delay (tpd)
• ±6mA Output drive at 5V
• 1µA maximum Low input current
• Green product and no Sb/Br
