FSTD16861
20-Bit Bus Switch with Level Shifting
General Description
The Fairchild Switch FSTD16861 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.
Features
s 4: 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
s Power-off high impedance inputs and outputs
s Supports live insertion/withdrawal (Note 1)
Note 1: To ensure the high-impedance state during power up or power
down, OE should be tied to VCC through a pull-up resistor; the minimum
value of the resistor is determined by the current-sourcing capability of the
driver.
