Overview
The CBTD3384PW is a dual 5-pole, single-throw bus switch produced by Nexperia (formerly part of NXP USA Inc.). This device is specifically designed for 5 V to 3.3 V level shifting applications, making it ideal for systems that require voltage translation between different logic levels.
The CBTD3384PW features two output enable inputs (nOE) that each control five switch channels, allowing for precise control over data transmission. The device is fully specified for partial power-down applications using IOFF circuitry, ensuring low power consumption when not in use.
