U74AC244L-P20-T Overview

OCTAL BUFFERS/DRIVERS WITH 3-STATE OUTPUTS

UNISONIC TECHNOLOGIES CO., LTD
U74AC244
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 V
CC
through a pull-up resistor; the
minimum value of the resistor is determined by the current-sinking
capability of the driver.
