(1) Component qualification in accordance with JEDEC and
industry standards to ensure reliable operation over an
extended temperature range. This includes, but is not limited
to, Highly Accelerated Stress Test (HAST) or biased 85/85,
temperature cycle, autoclave or unbiased HAST,
electromigration, bond intermetallic life, and mold compound
life. Such qualification testing should not be viewed as
justifying use of this component beyond specified
performance and environmental limits.

DESCRIPTION/ORDERING INFORMATION
The SN74ABT16245A-EP is a 16-bit noninverting 3-state transceiver designed for synchronous two-way
communication between data buses. The control-function implementation minimizes external timing
requirements.
This device can be used as two 8-bit transceivers or one 16-bit transceiver. It allows data transmission from the
A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR)
input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated.
When V_CC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down.
However, to ensure the high-impendance state above 2.1 V, OE should be tied to V_CC through a pullup resistor;
the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN74ABT16245A-EP is characterized for operation from –55°C to 125°C.
