FST162861 20-Bit Bus Switch with 25� Series Resistors in Outputs March 2000 Revised January 2005 FST162861 20-Bit Bus Switch with 25� Series Resistors in Outputs General Description Features The Fairchild Switch FST162861 provides 20-bits of high- ■ 25 switch connection between two ports. speed CMOS TTL-compatible bus switching. The low On ■ Minimal propagation delay through the switch. Resistance of the switch allows inputs to be connected to ■ Low l . CC outputs without adding propagation delay or generating ■ Zero bounce in flow-through mode. additional ground bounce noise. ■ Control inputs compatible with TTL level. The device is organized as a 10-bit or 20-bit bus switch. When OE is LOW, the switch is ON and Port 1A is con- 1 nected to Port 1B. When OE is LOW, Port 2A is connected 2 to Port 2B. When OE is HIGH, a high impedance state X exists between the A and B ports. The FST162861 has an equivalent 25 series resistors to reduce signal-reflection noise, eliminating the need for external terminating resis- tors.
