FSTD162861
20-Bit Bus Switch with Level Shifting
and 25 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 V
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.
