FSTD3306 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 TTLcompatible active LOW control inputs. The low on resistance of the switch allows inputs to be connected to outputs with minimal propagation delay and without 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 independent of VCC.
