OCTAL BUFFERS/DRIVERS

WITH 3STATE OUTPUTS

POST OFFICE BOX 655303

description/ordering information

These octal buffers and line drivers are designed

specifically to improve the performance and

density of 3-state memory address drivers, clock

drivers,

and

bus-oriented

receivers

and

transmitters.

The ’AC241 devices are organized as two 4-bit

buffers/drivers with separate complementary

output-enable (1OE and 2OE) inputs. When 1OE

is low or 2OE is high, the device passes

noninverted 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

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.
