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.
When OE₁ is LOW, the switch is ON and Port 1A is con-
nected to Port 1B. When OE₂ is LOW, Port 2A is connected
to Port 2B. When OE_1/2 is HIGH, a high impedance state
exists between the A and B Ports.
Features
s 4Ω switch connection between two ports
s Minimal propagation delay through the switch
s Low l_CC
s Zero bounce in flow-through mode
s Control inputs compatible with TTL level
s Also packaged in plastic Fine Pitch Ball Grid Array
(FBGA)
