SN74HCT125 (ACTIVE) Quadruple Bus Buffer Gates With 3-State Outputs

Quadruple Bus Buffer Gates With 3-State Outputs - SN74HCT125
Datasheet
 

Description

These 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

  • Operating Voltage Range of 4.5 V to 5.5 V
  • High-Current Outputs Drive Up To 15 LSTTL Loads
  • Low Power Consumption, 80-µA Max ICC
  • Typical tpd = 12 ns
  • ±6-mA Output Drive at 5 V
  • Low Input Current of 1 µA Max
  • Inputs Are TTL-Voltage Compatible
  • High-Current 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers
