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.

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
