SN74HCT125D .

The SN74HCT125D is a quadruple Bus Buffer Gate with 3-state outputs. It features independent line drivers with 3-state outputs. Each output is disabled when the associated OE\ input is high. To ensure the high-impedance state during power up or power down, OE\ should be tied to VCC through a pull-up resistor, the minimum value of the resistor is determined by the current-sinking capability of the driver.

• High-current outputs drive up to 15 LSTTL loads
• Typical tpd = 12ns
• Inputs are TTL-voltage compatible
• High-current 3-state outputs drive bus lines or buffer memory address registers
• 80µA Maximum low power consumption
• ±6mA Output drive at 5V
• 1µA Maximum low input current
• Green product and no Sb/Br
