QUADRUPLE BUS BUFFER
GATES WITH 3-STATE
OUTPUTS
DESCRIPTION
The U74LVC126A are quadruple bus buffer gates featuring
independent line drivers with 3-state outputs. When OE is low, the
nY outputs are in a high-impedance state. When OE is high, the
device passes non-inverted data from the nA input to its nY output.
To ensure the high-impedance state during power up or power
down, OE should be tied to GND through a pull-down resistor; the
minimum value of the resistor is determined by the current-sinking
capability of the driver.
Inputs can be driven from either 3.3V to 5V devices. This feature
allows the use of these devices as translators in a mixed 3.3V/5V
system environment.
FEATURES
* 1.65V to 3.6V VCC Operation
* Max tPD of 4.7ns from A to Y at VCC = 3.3V, CL = 50pF, RL = 500Ω
* ±24mA output driver at 3V

Note: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
