DESCRIPTION  
The 74ALVCH16245 is a low voltage CMOS 16  
BIT BUS TRANSCEIVER fabricated with  
sub-micron silicon gate and five-layer metal wiring  
2
C MOS technology. It is ideal for low power and  
very high speed 1.65 to 3.6V applications; it can  
be interfaced to 3.6V signal environment for both  
inputs and outputs.  
This IC is intended for two-way asynchronous  
communication between data busses; the  
direction of data transmission is determined by  
DIR input. The enable input G can be used to  
disable the device so that the busses are  
effectively isolated.  
Bus hold on data inputs is provided in order to  
eliminate the need for external pull-up or  
pull-down resistor.  
All inputs and outputs are equipped with  
protection circuits against static discharge, giving  
them 2KV ESD immunity and transient excess  
voltage.
