74LCX16240
Low Voltage 16-Bit Inverting Buffer/Line Driver with
5V Tolerant Inputs/Outputs
General Description
The LCX16240 contains sixteen inverting buffers with 3-
STATE outputs designed to be employed as a memory and
address driver, clock driver, or bus-oriented transmitter/
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 LCX16240 is designed for low voltage (2.5V or 3.3V)
VCC applications with capacity of interfacing to a 5V signal
environment.
The LCX16240 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.
Features
s 5V tolerant inputs and outputs
s 2.3V–3.6V VCC specifications provided
s 4.5 ns tPD max (VCC = 3.3V), 20 µA ICC max
s Power down high impedance inputs and outputs
s Supports live insertion/withdrawal (Note 1)
s ±24 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
Note 1: To ensure the high-impedance state during power up or down, OE
should be tied to VCC through a pull-up resistor: the minimum value or the
resistor is determined by the current-sourcing capability of the driver.

Note 2: 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 3: IO Absolute Maximum Rating must be observed.
Note 4: Unused inputs must be held HIGH or LOW. They may not float.
