Part Details:

FST3 February 2001 Revised February 2001 306 2-Bit FST3306 Low 2-Bit Low Power Bus Switch Power Bus General Description Features The FST3306 is a 2-bit ultra high-speed CMOS FET bus s Typical 3 switch resistance at 5.0V VCC switch with TTL-compatible active LOW control inputs. The s Minimal propagation delay through the switch low on resistance of the switch allows inputs to be con- s nected to outputs with minimal propagation delay and with- Power down high impedance input/output out generating additional ground bounce noise. The device s Zero bounce in flow through mode. is organized as a 2-bit switch with independent bus enable s TTL compatible active LOW control inputs Swi (BE) controls. When BE is LOW, the switch is ON and s Control inputs are overvoltage tolerant Port A is connected to Port B. When BE is HIGH, the t switch is OPEN and a high-impedance state exists ch between the two ports. Control inputs tolerate voltages upto 5.5V independent of VCC. Ordering Code: Order Number Package Number Package Description FST3306MTC MTC08 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.
