QUADRUPLE 3-STATE BUFFERS OE HIGH
Description
Pin Assignments
The 74HCT126 provides provides four independent buffer gates with
3-state outputs. Each buffer has a separate enable pin that if 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 4.5V to 5.5V.
