General Description

The Fairchild Universal Bus Switch FSTUD32450 provides 4-bit, 5-bit, 8-bit, 10-bit, 16-bit, 20-bit...40-bit of high-speed 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 FSTUD32450 is designed to allow “customer” configuration control of the enable connections.

Key Features

  • I Undershoot protected to.
  • 2V (A and B Ports) I Voltage level shifting I 4Ω switch connection between two ports I Minimal propagation delay through the switch I Low lCC I Zero bounce in flow-through mode I Control inputs compatible with TTL level I See.
