Dual Buffer/Driver With 3-State Outputs

 

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 bus-oriented 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.
