74AHC125 QUADRUPLE 3-STATE BUFFERS OE LOW Description Pin Assignments The 74AHC125 provides provides four independent buffer gates with 3-state outputs. Each buffer has a separate enable pin that when driven with a high logic level places the corresponding output in the high impedance state. The device is designed for operation with a power supply range of 2.0V to 5.5V. The inputs are tolerant to 5.5V allowing this device to be used in a mixed voltage environment. Features Wide Supply Voltage Range from 2.0V to 5.5V Outputs Sink or Source 8mA at V = 4.5V CC CMOS Low Power Consumption Schmitt Trigger Action at All Inputs Inputs can be driven by 3.3 V or 5.5V allowing for voltage translation applications.
