description

This octal buffer/line driver is designed for 2.7-V to 3.6-V V_CC operation.

The SN74LVC241A is designed specifically to improve both the performance and density of 3-state memory-address drivers, clock drivers, and bus-oriented receivers and transmitters. Together with the 'LVC240A and 'LVC244A, these devices provide the choice of selected combinations of inverting and noninverting outputs, symmetrical (active-low output-enable) inputs, and complementary OE and inputs.

The SN74LVC241A is organized as two 4-bit line drivers with separate output-enable (1, 2OE) inputs. When 1 is low or 2OE is high, the device passes data from the A inputs to the Y outputs. When 1 is high or 2OE is low, the outputs are in the high-impedance state.

To ensure the high-impedance state during power up or power down, should be tied to V_CC 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.

Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment.

The SN74LVC241A is characterized for operation from -40°C to 85°C.
