74LCX2244
Low Voltage Buffer/Line Driver with 5V Tolerant Inputs
and Outputs with 26Ω Series 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 26Ω-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 26Ω-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.
