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.
