(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
This 16-bit (dual-octal) noninverting bus transceiver contains two separate supply rails. B port has V_CCB, which is
set to operate at 3.3 V and 5 V. A port has V_CCA, which is set to operate at 2.5 V and 3.3 V. This allows for
translation from a 2.5-V to a 3.3-V environment, and vice versa, or from a 3.3-V to a 5-V environment, and vice
versa.
The SN74ALVC164245 is designed for asynchronous communication between data buses. The control circuitry
(1DIR, 2DIR, 1OE, and 2OE) is powered by V_CCA.
To ensure the high-impedance state during power up or power down, the output-enable (OE) input 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.
