SN74HC125N, Буферы и линейные аппаратные драйверы Quad Bus [PDIP14]
The SN74HC125N is a quadruple Bus Buffer Gate features independent line drivers with 3-state outputs. It is designed for 2 to 6V 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 pull-up resistor and the minimum value of the resistor is determined by the current-sinking 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
