DESCRIPTION:

FEATURES:

• Std. and A speed grades

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. Theseoctalbustransceiversaredesignedfor

asynchronous two-way communication between data buses.

The control function implementation allows for maximum

flexibility in timing.

• Low input and output leakage ≤1µA (max.)

• CMOS power levels

• True TTL input and output compatibility

– VOH = 3.3V (typ.)

– VOL = 0.3V (typ.)

• Power off disable outputs permit “live insertion”

• Meets or exceeds JEDEC standard 18 specifications

• Product available in Radiation Tolerant and Radiation

Enhanced versions

• Military product compliant to MIL-STD-883, Class B

and DESC listed (dual marked)

• Available in DIP, SOIC, CERPACK and LCC packages
