74LCX162244
Low Voltage 16-Bit Buffer/Line Driver
with 26Ω Series Resistors in Outputs
General Description
The LCX162244 contains sixteen non-inverting buffers with
3-STATE outputs designed to be employed as a memory
and address driver, clock driver, or bus oriented transmit-
ter/receiver. The device is nibble controlled. Each nibble
has separate 3-STATE control inputs which can be shorted
together for full 16-bit operation.
The LCX162244 is designed for low voltage (2.5V or 3.3V)
VCC applications with capability of interfacing to a 5V signal
environment.
In addition, the outputs include equivalent 26Ω (nominal)
series resistors to reduce overshoot and undershoot and
are designed to sink/source up to 12 mA at VCC = 3.0V.
The LCX162244 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation.
Features
s 5V tolerant inputs and outputs
s 2.3V–3.6V VCC specifications provided
s Outputs include equivalent series resistance of 26Ω to
make external termination resistors unnecessary and
reduce overshoot and undershoot
s 5.3 ns tPD max (VCC = 3.0V), 20 µA ICC max
s Power down high impedance inputs and outputs
s ±12 mA output drive (VCC = 3.0V)
s Implements patented noise/EMI reduction circuitry
s Latch-up performance exceeds 500 mA
s ESD performance:
Human body model > 2000V
Machine model > 200V
s Also packaged in plastic Fine-Pitch Ball Grid Array
(FBGA) (Preliminary)

Note 3: 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 Ratings. The “Recom-
mended Operating Conditions” table will define the conditions for actual device operation.
Note 4: IO Absolute Maximum Rating must be observed.
Note 5: Unused control inputs must be held HIGH or LOW. They may not float.
