The ON Semiconductor 74FST3345 is an 8-bit high performance switch with extremely low RON and adds nearly zero propagation delay. The device adds no noise or ground bounce to the system and consists of an 8-bit switch with two Output/Enable pins (OE and OE).
The document describes the ON Semiconductor 74FST3345, an 8-bit high-performance bus switch designed for operation between 4.0V and 5.5V. The device features extremely low on-resistance (Ron < 42 Ohms typical) and adds nearly zero propagation delay to the system. It is pin-for-pin compatible with several other models including QS3345, FST3345, and CBT3345.
