74FCT621T

IDT74FCT621T/AT FAST CMOS OCTAL BUS TRANSCEIVER (OPEN DRAIN) FAST CMOS OCTAL BUS TRANSCEIVER (OPEN DRAIN) INDUSTRIAL TEMPERATURE RANGE IDT74FCT621T/AT FEATURES: 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 DESCRIPTION: 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.
