3 Description

This dual buffer and line driver is designed for 1.65-V

to 5.5-V VCC operation.

The SN74LVC2G241 device is designed specifically

to improve both the performance and density of 3-

state memory-address drivers, clock drivers, and busoriented

receivers and transmitters.

NanoFree package technology is a major

breakthrough in IC packaging concepts, using the die

as the package.

The SN74LVC2G241 device is organized as two 1-bit

line drivers with separate output-enable (1OE, 2OE)

inputs. When 1OE is low and 2OE is high, the device

passes data from the A inputs to the Y outputs. When

1OE is high and 2OE is low, the 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

pullup resistor, and OE should be tied to GND

through a pulldown resistor; the minimum value of the

resistor is determined by the current-sinking or the

current-sourcing capability of the driver.

This device is fully specified for partial-power-down

applications using Ioff. The Ioff circuitry disables the

outputs, preventing damaging current backflow

through the device when it is powered down.
