Overview
The SN74LVCC3245APWR is an 8-bit (octal) noninverting bus transceiver produced by Texas Instruments. This device is designed with two separate supply rails, allowing it to perform bidirectional voltage translation between different system environments. The A port operates at voltages from 2.3 V to 3.6 V, while the B port accepts voltages from 3 V to 5.5 V, enabling translation from a 3.3-V to a 5-V system and vice versa, as well as from a 2.5-V to a 3.3-V system and vice versa.
