QUADRUPLE 3-STATE BUFFERS OE HIGH
Description
The 74AHC126 provides provides four independent buffer gates with
3-state outputs. Each buffer has a separate enable pin that when
driven with a low 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
CC
= 4.5V
• CMOS Low Power Consumption
• Schmitt Trigger Action at All Inputs
• Inputs can be driven by 3.3V or 5.5V allowing for voltage
translation applications.
• ESD Protection Exceeds JESD 22
ƒ 200-V Machine Model (A115-A)
ƒ 2000-V Human Body Model (A114-A)
