description
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.
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.
