OCTAL BUS TRANSCEIVER

(OPEN DRAIN)

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.
