Quadruple Bus Buffer Gates With 3-State Outputs

 

Description

The SNx4HC125 device is a quadruple set of bus buffer gates and features independent line drivers with 3-state outputs. The SNx4HC125 is designed for 2-V to 6-V VCC operation. 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.

Features

  • Wide Operating Voltage Range of 2 V to 6 V
  • High-Current 3-State Outputs Interface Directly
    With System Bus or Can Drive Up to 15 LSTTL
    Loads
  • Low Power Consumption, 80-µA Maximum ICC
  • Typical tpd = 11 ns
  • ±6-mA Output Drive at 5 V
  • Low Input Current of 1 µA Maximum
