2-Bit Low Power Bus Switch with Level Shifting
General Description
The FSTD3306 is a 2-bit ultra high-speed CMOS FET bus
switch with enhanced level shifting circuitry and with TTL-
compatible active LOW control inputs. The low on resis-
tance of the switch allows inputs to be connected to out-
puts
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. Reduced voltage drive to the gate of the FET switch
permits nominal level shifting of 5V to 3V through the
switch. Control inputs tolerate voltages up to 5.5V indepen-
dent of V
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
