FST3306 2-Bit Low Power Bus Switch February 2001 Revised February 2001 FST3306 2-Bit Low Power Bus Switch General Description The FST3306 is a 2-bit ultra high-speed CMOS FET bus switch with TTL-patible active LOW control inputs. The low on resistance of the switch allows inputs to be connected to outputs with minimal propagation delay and without generating additional ground bounce noise. The device is organized as a 2-bit switch with independent bus enable (BE) controls. When BE is LOW, the switch is ON and Port A is connected to Port B. When BE is HIGH, the switch is OPEN and a high-impedance state exists between the two ports. Control inputs tolerate voltages up to 5.5V independent of VCC. Features s Typical 3Ω switch resistance at 5.0V VCC s Minimal propagation delay through the switch s Power down high impedance input/output s Zero bounce in flow through mode. s TTL patible active LOW control inputs s Control inputs are overvoltage tolerant Ordering Code: Order Number FST3306MTC Package Number MTC08 Package Description 8-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
