CBTD3306 is a dual bus switch produced by Philips Semiconductors. It features 5 ohms switch connection, TTL-compatible input levels, and internal diode. The switch is suitable for 5V to 3.3V level shifting applications. It has ESD protection of 2000V HBM and 1000V CDM.
The Philips CBTD3306 is an integrated circuit designed as a dual FET bus switch with internal level shifting capabilities. It facilitates signal transfer between two ports while supporting voltage transitions from 5 V to 3.3 V applications, utilizing an internal diode for the shift function.
The device features independent line switches that can be disabled via associated Output Enable (OE) inputs. It is characterized for operation over a wide temperature range of -40 to +85 °C and includes protection against latch-up and electrostatic discharge (ESD). The component is offered in 8-pin plastic small outline (SO) and thin shrink small outline (TSSOP) packages.
