FSLV16211 — 24-Bit Bus Switch Features Description The FSLV16211 is a 24-bit, high-speed, low-voltage bus switch. The low on resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. 5Ω Switch Connection between Two Ports Minimal Propagation Delay through the Switch Low lCC Zero Bounce in Flow-Through Mode Packaged in Thin-Shrink Small Outline Package (TSSOP) This design can be used as a 12- or 24-bit bus switch. When /OE1 is LOW, port 1A is connected to Port 1B. When /OE2 is LOW, port 2A is connected to Port 2B.

The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
