Overview
Preliminary FST162244 16-Bit Bus Switch with 25Ω Series Resistor in Outputs (Preliminary) May 2001 Revised May 2001 FST162244 16-Bit Bus Switch with 25Ω Series Resistor in Outputs (Preliminary) General Description The Fairchild Switch FST162244 provides 16-bits of highspeed CMOS TTL-compatible bus switching.
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.
There are four 4-bit switches with separate output enable inputs.
When OE is LOW, the switch in ON and Port A is connected to Port B.
When OE is HIGH, the switch OFF and a high impedance state exists between the A and B Ports.
The FST162244 has an equivalent 25Ω series resistors to reduce signal-reflection noise, eliminating the need for external terminating resistors.
Features s 25Ω 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.
