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 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. Control inputs tolerate voltages up to 5.5V independent of VCC.
The FST3306 is a 2-bit ultra high-speed CMOS FET bus switch designed with TTL-compatible active LOW control inputs. It features a low on-resistance of typically 3 ohms at 5.0V, allowing 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, where a LOW signal connects Port A to Port B, and a HIGH signal places the switch in an open, high-impedance state.
| Supply Voltage (Operating) | 4.0V to 5.5V |
|---|---|
| Package Type | 8-Lead Thin Shrink Small Outline Package (TSSOP) |
| Control Input Type | TTL-compatible active LOW |
When the Bus Enable (BE) input is LOW, the switch is ON and Port A is connected to Port B. When BE is HIGH, the switch is OPEN.
The absolute maximum rating for supply voltage is +7.0V.
