Octal Bus Transceiver and Voltage Translator IC SN74LVC4245APWR

Description

The SN74LVC4245APWR is a bidirectional octal (8‑bit) bus transceiver and voltage level translator that supports communication between different logic voltage levels (e.g., 3.3 V ↔ 5 V). It contains separate supply rails for each port:

• A‑Port (VCCA): up to 5.5 V

• B‑Port (VCCB): 2.7 V to 3.6 V

The direction of data transfer is controlled by the DIR (direction) input, and the outputs can be disabled via the OE (output enable) for bus isolation.
