FST3384: 10-Bit Low Power Bus Switch

The Fairchild Switch FST3384 provides 10 bits of high-speed CMOS TTL-compatible bus switches. The low on resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. The device is organized as two 5-bit switches with separate bus enable (OE#) signals. When OE# is LOW, the switch is ON and Port A is connected to Port B. When OE# is HIGH, the switch is OPEN and a high-impedance state exists between the two ports.

Features

• 4ohm switch connection between two ports
• Minimal propagation delay through the switch
• Ultra low power with <0.1 µA typical I_CC
• Zero ground bounce in flow-through mode
• Control inputs compatible with TTL level
