onsemi Signal Switches, Multiplexers, Decoders FST3126MX

The FST3126 is a 4-bit bus switch designed for high-speed CMOS TTL-compatible applications. It features four independent 1-bit switches with separate enable (OE) inputs, allowing for flexible control of signal routing. When the OE input is high, the switch connects Port A to Port B, while a low OE input places the switch in a high-impedance state. The device boasts a low on-resistance of approximately 4 to 7 ohms, minimal propagation delay, and zero ground bounce in flow-through mode, making it suitable for high-performance digital circuits. The FST3126 operates within a supply voltage range of 4.0V to 5.5V and can handle input and output voltages from 0V to 5.5V. It is rated for a storage temperature range of -65¬8C to +150¬8C and has a quiescent supply current of just 3 ¬µA. The device is available in multiple package options, including 14-lead SOIC, 16-lead QSOP, and 14-lead TSSOP, with tape and reel options for automated assembly. This product is ideal for applications requiring efficient signal switching with minimal delay and power consumption.
