74ALVC16244
Low Voltage 16-Bit Buffer/Line Driver
with 3.6V Tolerant Inputs and Outputs
General Description
The ALVC16244 contains sixteen non-inverting buffers with
3-STATE outputs to be employed as a memory and
address driver, clock driver, or bus oriented transmitter/
receiver. The device is nibble (4-bit) controlled. Each nibble
has separate 3-STATE control inputs which can be shorted
together for full 16-bit operation.
The 74ALVC16244 is designed for low voltage (1.65V to
3.6V) V
CC
applications with I/O capability up to 3.6V.
The 74ALVC16244 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.

Note 1:
To ensure the high-impedance state during power up or power
down, OE should be tied to V

through a pull-up resistor; the minimum
value of the resistor is determined by the current-sourcing capability of the
driver.

Functional Description
The 74ALVC16244 contains sixteen non-inverting buffers
with 3-STATE outputs. The device is nibble (4 bits) con-
trolled with each nibble functioning identically, but indepen-
dent of each other. The control pins may be shorted
together to obtain full 16-bit operation.The 3-STATE out-
puts are controlled by an Output Enable (OE
n
) input. When
OE
n
is LOW, the outputs are in the 2-state mode. When
OE
n
is HIGH, the standard outputs are in the high imped-
ance mode but this does not interfere with entering new
data into the inputs.

Note 4:
The Absolute Maximum Ratings are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the Absolute Maximum Rat-
ings. The “Recommended Operating Conditions” table will define the condi-
tions for actual device operation.
Note 5:
