74ALVC16244 Low Voltage 16-Bit Buffer/Line Driver with 3.6V Tolerant Inputs and Outputs
74ALVC16244
Low Voltage 16-Bit Buffer/Line Driver
with 3.6V Tolerant Inputs and Outputs
General Descript ion
The AL VC16244 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- S TATE con tro l inpu ts which can be sh orted
together for full 16-bit operation.
The 74ALVC16244 is designed for low voltage (1.65V to
3.6V) VCC applications with I/O capability up to 3.6V.
The 74ALVC16 244 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 VCC through a pull-up resistor; the minimum
value of th e resistor is determin ed by the curr ent-so urcing capab ility of the
driver.
