FST34X2245 32-Bit Bus Switch with 25Ω Series Resistors in Outputs December 2001 Revised December 2001 FST34X2245 32-Bit Bus Switch with 25Ω Series Resistors in Outputs General Description Features The Fairchild Switch FST34X2245 provides 32-bits of high25Ω switch connection between two ports speed CMOS TTL-compatible bus switching in a standardMinimal propagation delay through the switch flow-through mode. The low On Resistance of the switch Low l CC allows inputs to be connected to outputs without adding Zero bounce in flow-through mode propagation delay or generating additional ground bounce noise.Control inputs compatible with TTL level The device is organized as a 32-bit switch. When OE is32-bit version of FST32245 LOW, the switch is ON and Port A is connected to Port B. Packaged in 20.5mm 80-lead package When OE is HIGH, the switch is OPEN and a high-imped- ance state exists between the two ports. The FST34X2245 has equivalent 25Ω series resistors to reduce signal-reflection noise, eliminating the need for external terminating resistors.
