74LCX2244
Low Voltage Buffer/Line Driver with 5V Tolerant Inputs
and Outputs with 26Series Resistors in the Outputs
General Description
The LCX2244 contains eight non-inverting buffers with 3-
STATE outputs. The device may be employed as a mem-
ory address driver, clock driver and bus-oriented transmit-
ter/receiver. The LCX2244 is designed for low voltage
(2.5V or 3.3V) VCC applications with capability of interfac-
ing to a 5V signal environment. The 26-series resistors
help reduce output overshoot and undershoot.
The LCX2244 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 7.5 ns tPD max (VCC = 3.3V) 10 µA ICC max
s Power down high impedance inputs and outputs
s 26-series resistors in the outputs
s Supports live insertion/withdrawal (Note 1)
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
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.
