IDT74FCT621T/AT FAST CMOS OCTAL BUS TRANSCEIVER (OPEN DRAIN) INDUSTRIAL TEMPERATURE RANGE FAST CMOS OCTAL BUS TRANSCEIVER (OPEN DRAIN) FEATURES: IDT74FCT621T/AT DESCRIPTION: • • • • Std. and A grades Low input and output leakage ≤1µA (max.) CMOS power levels True TTL input and output compatibility: – VOH = 3.3V (typ.) – VOL = 0.3V (typ.) • Meets or exceeds JEDEC standard 18 specifications • Power off disable outputs permit "live insertion" • Available in SOIC package The IDT74FCT621T is an octal transceiver with non-inverting OpenDrain 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.
