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 8-bit (octal) noninverting bus transceiver contains two separate supply rails. The B port is designed to track
V_CCB, which accepts voltages from 3 V to 5.5 V, and the A port is designed to track V_CCA, which operates at
2.3 V to 3.6 V. This allows for translation from a 3.3-V to a 5-V system environment and vice versa, from a 2.5-V
to a 3.3-V system environment and vice versa.
The SN74LVCC3245A 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 are
isolated. The control circuitry (DIR, OE) is powered by V_CCA.
