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) V
CC
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.

through a pull-up resistor: the minimum value or the
resistor is determined by the current-sourcing capability of the driver.
