FSTU16861 - 20-Bit Bus Switch with −2V Undershoot Protection

Description

The Fairchild Switch FSTU16861 provides 20-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.

Features

  • s Undershoot hardened to.
  • 2V (A and B Ports) 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 See.

FSTU16861 20-Bit Bus Switch with −2V Undershoot Protection May 2001 Revised May 2001 FSTU16861 20-Bit Bus Switch with −2V Undershoot Protection General Description The Fairchild Switch FSTU16861 provides 20-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 10-bit or 20-Bit bus switch. When OE1 is LOW, the switch is ON and Port 1A is connected to Port 1B. When OE2 is LOW, Port 2A is connected to Port 2B. When OEX is HIGH, a high impedance state exists between the A and B Ports. The A and B Ports are protected against undershoot to support an extended range to 2.0V below ground.
