DESCRIPTION:
The IDT74FCT621T is an octal transceiver with non-inverting Open-
Drain bus compatible outputs in both send and receive directions. The B
bus outputs are capable of sinking 64mA providing very good capacitive
drive characteristics. These octal bus transceivers are designed for
asynchronous two-way communication between data buses. The control
function implementation allows for maximum flexibility in timing.
