FST3306
2-Bit Low Power Bus Switch
General Description
The FST3306 is a 2-bit ultra high-speed CMOS FET bus
switch with TTL-compatible active LOW control inputs. The
low on resistance of the switch allows inputs to be con-
nected to outputs with minimal propagation delay and with-
out generating additional ground bounce noise. The device
is organized as a 2-bit switch with independent bus enable
(BE) controls. When BE is LOW, the switch is ON and
Port A is connected to Port B. When BE is HIGH, the
switch is OPEN and a high-impedance state exists
between the two ports. Control inputs tolerate voltages up
to 5.5V independent of VCC.
Features
s Typical 3Ω switch resistance at 5.0V VCC
s Minimal propagation delay through the switch
s Power down high impedance input/output
s Zero bounce in flow through mode.
s TTL compatible active LOW control inputs
s Control inputs are overvoltage tolerant
