FSTD16211
24-Bit Bus Switch with Level Shifting
General Description
The Fairchild Switch FSTD16211 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. A diode to V_CC has been
integrated into the circuit to allow for level shifting between
5V inputs and 3.3V outputs.
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 Voltage level shifting
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)
