Quadruple Bus Buffer Gates With 3-State Outputs - SN74HC125

SN74HC125 (ACTIVE)

Quadruple Bus Buffer Gates With 3-State Outputs

Description

These quadruple bus buffer gates 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.

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 Max ICC
  • Typical tpd = 11 ns
  • ±6-mA Output Drive at 5 V
  • Low Input Current of 1 µA Max
