74AHC126
QUADRUPLE 3-STATE BUFFERS
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.
