FST32X245 16-Bit Bus Switch June 2002 Revised October 2002 FST32X245 16-Bit Bus Switch General Description The Fairchild Switch FST32X245 provides 16-bits of high speed CMOS TTL-compatible bus switching in a standard flow-through mode. The low On Resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. The device is organized as a 16-bit switch. When OE is LOW, the switch is ON and Port A is connected to Port B. When OE is HIGH, the switch is OPEN and a high-impedance state exists between the two ports. Features s 4Ω switch connection between two ports s Minimal propagation delay through the switch s Low lCC s Zero bounce in flow-through mode s Control inputs compatible with TTL level s 16-bit version of FST3245 Ordering Code: Order Number FST32X245QSP Package Number MQA40A Package Description 40-Lead Quarter Size Very Small Outline Package (QVSOP), JEDEC MO-154, 0.150" Wide Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
