OCTAL BUS TRANSCEIVER
(OPEN DRAIN)
DESCRIPTION:
The IDT54/74FCT621T/AT 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.
