FST16211

24-Bit Bus Switch

General Description

The Fairchild Switch FST16211 provides 24-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 is organized as a 12-bit or 24-bit bus switch.

exists between the A and B Ports.

Features

■ 4

Ω switch connection between two ports

■ Minimal propagation delay through the switch

■ Zero bounce in flow-through mode

■ Control inputs compatible with TTL level

■ Also packaged in plastic Fine-Pitch Ball Grid Array

(FBGA)

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.
