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.  
It has more speed performance at 3.3V than 5V  
AC/ACT family, combined with a lower power  
consumption.  
All inputs are equipped with protection circuits  
against static discharge, giving them 2KV ESD  
immunity and transient excess voltage.  
All floating bus terminals during High Z State must  
be held HIGH or LOW.  
DESCRIPTION  
The 74LVC245A is a low voltage CMOS OCTAL  
BUS TRANSCEIVER (3-STATE) fabricated with  
sub-micron silicon gate and double-layer metal

wiring C MOS technology. It is ideal for 1.65 to 3.6

applications.  
This IC is intended for two-way asynchronous  
communication between data buses and the
