500mA (JESD 17)  
It has same speed performance at 3.3V than 5V  
AC/ACT family, combined with a lower power  
consumption.  
ESD PERFORMANCE:  
This IC is intended for two way asynchronous  
communication between data buses; the direction  
of data transmission is determined by DIR input.  
The enable input G can be used to disable the  
device so that the buses are effectively isolated.  
All inputs and outputs are equipped with  
protection circuits against static discharge, giving  
them 2KV ESD immunity and transient excess  
voltage.  
HBM > 2000V (MIL STD 883 method 3015);  
MM > 200V  
DESCRIPTION  
The 74LCX245 is a low voltage CMOS OCTAL  
BUS TRANSCEIVER (3-STATE) fabricated with  
sub-micron silicon gate and double-layer metal  
2
wiring C MOS technology. It is ideal for low power  
and high speed 3.3V applications; it can be  
interfaced to 5V signal environment for both inputs  
and outputs.  
All floating bus terminals during High Z state must  
be held HIGH or LOW.
