DESCRIPTION
The LCX244 is a low voltageCMOS OCTALBUS
BUFFER
(NON-INVERTED)
sub-micron silicon gate and double-layer metal
wiring C
2
MOS technology. It is ideal for low
power and high speed 3.3V applications; it can
be interfaced to 5V signal enviroment for both
fabricated
with
T
(TSSOP Package)
inputsand outputs.
It has same speed performance at 3.3V than 5V
AC/ACT family, combined with a lower power
consumption.
This device is designed to be used with 3 state
memory address drivers, etc.
All
inputs and
outputs
protectioncircuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
are
equipped with
PINCONNECTION AND IEC LOGICSYMBOLS
