FST32211 - 40/48-Bit Bus Switch

Download the FST32211 datasheet PDF. This datasheet also covers the FST variant, as both devices belong to the same 40/48-bit bus switch family and are provided as variant models within a single manufacturer datasheet.

Description

The Fairchild Switch FST32211 provides up to 48-bits 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.

Features

  • 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 Packaged in plastic Fine Pitch Ball Grid Array (FBGA) Ordering Code: Order Number FST32211G (Note 1)(Note 2) Package Number BGA114A Package.

FST32211 40/48-Bit Bus Switch April 2001 Revised July 2002 FST32211 40/48-Bit Bus Switch General Description The Fairchild Switch FST32211 provides up to 48-bits 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 device can be organized as four 12-bit, two 24-bit, or one 48-bit bus switch. When routed as a 40-bit bus switch, the device can be organized as four 10-bit, two 20-bit or one 40-bit bus switch. When OE1 is LOW, the switch is ON and Port 1A is connected to Port 1B. When OE2 is LOW, the switch is ON and Port 2A is connected to Port 2B. When OE3 is LOW, the switch is ON and Port 3A is connected to Port 3B.
