SN74LVCC3245A-EP - Enhanced Product Octal Bus Transceiver With Adjustable Output Voltage And 3-State Outputs

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.

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.
