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