The FSTU16861MTDX is a 20-bit bus switch designed for high-speed CMOS TTL-compatible applications. It features low on-resistance, allowing for minimal propagation delay and reduced ground bounce noise when connecting inputs to outputs. The device can be configured as either a 10-bit or 20-bit switch, with control inputs that enable or disable the connection between ports. When the enable signals (OE1 or OE2) are low, the corresponding ports are connected; when high, the switch enters a high-impedance state. This bus switch is undershoot-hardened, providing protection against voltage undershoot down to -2V, which enhances its reliability in various applications. The device 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 housed in a 48-lead Thin Shrink Small Outline Package (TSSOP), making it suitable for space-constrained designs. The FSTU16861MTDX is ideal for applications requiring efficient signal routing with minimal delay and noise.
