FSTD162861
20-Bit Bus Switch with Level Shifting
and 25Ω Series Resistors in Outputs (Preliminary)
General Description
The Fairchild Switch FSTD162861 provides 20-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 VCC has been
integrated into the circuit to allow for level shifting between
5V inputs and 3.3V outputs.
The device is organized as a 10-bit or 20-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 OEX is HIGH, a high impedance state
exists between the A and B Ports. The FSTD162861 has
equivalent 25Ω series resistors to reduce signal-reflection
noise, eliminating the need for external terminating resis-
tors.
Features
s 25Ω switch connection between two ports
s Minimal propagation delay through the switch
s Low lCC
s Zero bounce in flow-through mode
s Control inputs compatible with TTL level
s TruTranslation voltage translation from 5.0V inputs to
3.3V outputs
