description  
GND  
These octal bus transceivers are designed for  
asynchronous two-way communication between  
data buses. These devices transmit data from the A bus to the B bus or from the B bus to the A bus, depending  
upon the level at the direction-control (DIR) input. The output-enable (OE) input disables the device so that the  
buses are effectively isolated.  
The -1 versions of the SN74ALS641A and SN74ALS642A are identical to the standard versions, except that  
the recommended maximum I is increased to 48 mA in the -1 versions.  
OL  
The SN74ALS641A, SN74ALS642A, and SN74AS641 are characterized for operation from 0°C to 70°C.
