3 Description

The SN74LVCC3245A device is 8-bit (octal) noninverting bus transceiver contains two separate supply rails. The B port is designed to track VCCB, which accepts voltages from 3 V to 5.5 V, and the A port is designed to track VCCA, 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.
