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 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.
