| FSLV16211 24-Bit Bus Switch February 2001 Revised March 2003 FSLV16211 24-Bit Bus Switch General 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. This device's design allow this part to be used as a 12-bit 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. Features s 5 switch connection between two ports s Minimal propagation delay through the switch s Low lCC s Zero bounce in flow-through mode s Also packaged in plastic Fine-Pitch Ball Grid Array (FBGA) Ordering Code: Order Number FSLV16211G (Note 1)(Note 2) FSLV16211MTD (Note 2) Package Number BGA54A MTD56 Package Description 54-Ball Fine-Pitch Ball Grid Array (FBGA), JEDEC MO-205, 5.5mm Wide 56-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 6.1mm Wide Note 1: Ordering code "G" indicates Trays. Note 2: Devices also available in Tape and Reel. Specify by appending the suffix letter "X" to the ordering code.

The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum rating. The "Recommended Operating Conditions" table will define the conditions for actual device operation. Note 4: The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed. Note 5: Unused control inputs must be held HIGH or LOW. They may not float.
