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 OE

and Port 1A is connected to Port 1B. When OE

the switch is ON and Port 2A is connected to Port 2B.

When OE

nected to Port 3B. When OE

Port 4A is connected to Port 4B. When OE

A and B Ports.

Ordering Code:

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.
