1 / 6 page IDT54/74FCT621T/AT FAST CMOS OCTAL BUS TRANSCEIVER (OPEN DRAIN) MILITARY AND COMMERCIAL TEMPERATURE RANGES 6.18 1 Integrated Device Technology, Inc. FAST CMOS 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.
