(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 SN74LVCC4245A is an 8-bit (octal) noninverting bus transceiver that uses two separate power-supply rails.
The A port (V_CCA) is dedicated to accepting a 5-V supply level, and the configurable B port, which is designed to
track V_CCB, accepts voltages from 3 V to 5 V. This allows for translation from a 3.3-V to a 5-V environment and
vice versa.
The SN74LVCC4245A is designed for asynchronous communication between data buses. The device transmits
data 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 the buses
effectively are isolated. The control circuitry (DIR, OE) is powered by V_CCA.
