The FSTU16245MTDX is a 16-bit bus switch designed for high-speed CMOS TTL-compatible applications. It features two 8-bit switches with separate output enable inputs, allowing for flexible control of signal routing. When the output enable (OE) is LOW, the switch connects Port A to Port B, while a HIGH OE results in a high-impedance state between the ports. The device is equipped with undershoot protection, capable of handling voltage undershoots up to -2V, which enhances reliability in various applications. With a low on-resistance, the FSTU16245MTDX minimizes propagation delay and ground bounce noise, making it suitable for high-performance environments. The switch operates within a supply voltage range of 4.0V to 5.5V and supports input and output voltages from 0V to 5.5V. It is packaged in a 48-lead Thin Shrink Small Outline Package (TSSOP), facilitating integration into compact designs. The device is also characterized by low quiescent supply current and zero bounce in flow-through mode, contributing to efficient power management.
