2G  
The SN54ACT16245 and 74ACT16245 are 16-bit  
bus transceivers organized as dual-octal  
noninverting 3-state transceivers and designed  
for asynchronous two-way communication  
between data buses. The control-function  
implementation minimizes external timing  
requirements.  
GND  
2B7  
2B8  
2DIR  
The devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending on  
the logic level at the direction-control (DIR) input. The enable (G) input can be used to disable the devices so  
that the buses are effectively isolated.  
The SN54ACT16245 is characterized for operation over the full military temperature range of –55°C to 125°C.  
The 74ACT16245 is characterized for operation from –40°C to 85°C.
