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.
