CMOS IC
DUAL BUFFER/DRIVER WITH
3-STATE OUTPUTS
DESCRIPTION
The U74LVC2G240 is a dual buffer or driver with 3-state
outputs. It is designed for 1.65V to 5.5V operation.
The U74LVC2G240 is composed of two 1-bit buffers/drivers
with separate output-enable (
data passes from A (input) to Y (output). When
outputs are in the high-impedance state.
To ensure the high-impedance state during power up or power
down, OE should be tied to VCC through a pull-up resistor, and
the minimum value of the resistor is determined by the
current-sinking capability of the driver.
The U74LVC2G240 is fully specified for partial-power-down
applications using I
and prevents damaging current backflow through the device
when it is powered down.
