PI74ALVTC16244
1.8/2.5/3.3V 16-Bit Buffer/Driver
with 3-State Outputs
ProductFeatures
ProductDescription
• PI74ALVTC family is designed for low voltage operation,
VDD =1.8Vto3.6V
The PI74ALVTC16244 buffer/driver is designed specifically to
improve both the performance and density of 3-state memory
address drivers, clock drivers, and bus-oriented receivers and
transmitters.
• Supports Live Insertion
• 3.6V I/O Tolerant Inputs and Outputs
• Bus Hold
Thedevicecanbeusedasfour4-bitbuffers,two8-bitbuffers,orone
16-bit buffer. It provides true outputs and symmetrical active-low
output-enable (OE) inputs.
• HighDrive,-32/64mA@3.3V
• Uses patented noise reduction circuitry
• Power-off high impedance inputs and outputs
• Industrial operation at –40°C to +85°C
• Packaging(Pb-free&Greenavailable):
–48-pin173milwideplastic TVSOP(K)
–48-pin240milwideplastic TSSOP(A)
To ensure the high-impedance state during power up or power
down, OE should be tied to Vdd through a pullup resistor; the
minimum value of the resistor is determined by the current-sinking
capability of the driver.
The family offers both I/O Tolerant, which allows it to operate in
mixed 1.8/3.6V systems, and “Bus Hold,” which retains the data
input’s last state whenever the data input goes to high-impedance,
preventing “floating” inputs and eliminating the need for pullup/
down resistors.

Waveform 1 is for an output with internal conditions
such that the output is LOW except when disabled by the
output control.
Waveform 2 is for an output with internal conditions
such that the output is HIGH except when disabled by
the output control.
All input pulses are supplied by generators having the
followingcharacteristics:PRR≤10MHz,ZO =50Ω,
tr ≤ 2ns, tf ≤ 2ns, measured from 10% to 90%, unless
