3 Description
The SN74LVC126A device is a quadruple bus buffer
gate designed for 1.65V to 3.6V VCC operation.
The SN74LVC126A device features independent line
drivers with 3-state outputs. Each output is disabled
when the associated output-enable (OE) input is low.
To ensure the high-impedance state during power up
or power down, OE must be tied to GND through a
pulldown resistor; the minimum value of the resistor
is determined by the current-sourcing capability of the
driver.
Inputs can be driven from either 3.3V or 5V
devices. This feature allows the use of this device
as a translator in a mixed 3.3V and 5V system
environment.
