OCTAL BUFFERS/DRIVERS
WITH 3-STATE OUTPUTS
„ DESCRIPTION
The U74AC244 is a octal buffers/drivers with 3-state outputs. It is
organized as two 4-bit buffers/drivers with separate output-enable
( OE ) inputs. When OE is high, the Y outputs are in a
high-impedance state, and the outputs neither load nor drive the bus
lines. When OE is low, the device passes noninverted data from
the A inputs to the Y outputs.
The U74AC244 is designed to improve the performance and
density of 3-state memory address drivers, clock drivers, and
bus-oriented receivers and transmitters.
To ensure the high-impedance state during power up or power
down, OE should be tied to VCC through a pull-up resistor; the
minimum value of the resistor is determined by the current-sinking
capability of the driver.
„ FEATURES
* Wide supply voltage range from 2V to 6V
* Max tpd of 7 ns from A to Y at 5V
* Low power consumption, ICC = 4 μA (Max.) at 5.5V
* ±24 mA output driver at 5.5V
