FSTD3306

. Typical 3Ω switch resistance at 5.0V VCC, VIN = 0V
. Level shift facilitates 5V to 3.3V interfacing
. Minimal propagation delay through the switch
. Power down high impedance input/output
. Zero bounce in flow through mode
. TTL compatible active LOW control inputs
. Control inputs are overvoltage tolerant

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 with minimal propagation delay and without generating additional ground bounce noise. The FSTD3306 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 FSTD3306 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 .CC
