description

The SN74ACT16245Q-EP is a 16-bit bus

transceiver 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 device allows 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.
