onsemi Signal Switches, Multiplexers, Decoders 74FST3251DTR2

The 74FST3251DTR2 is an 8:1 multiplexer/demultiplexer bus switch designed for high performance applications. It operates within a supply voltage range of 4.0 to 5.5 volts and is compatible with both TTL and CMOS logic levels. The device features a low on-resistance (RON) of approximately 4 ohms, ensuring minimal signal degradation. It also boasts a maximum propagation delay of less than 0.25 nanoseconds, contributing to its high-speed performance. This bus switch is characterized by nearly zero standby current and no circuit bounce, making it suitable for applications where power efficiency and signal integrity are critical. The control inputs are TTL/CMOS compatible, allowing for easy integration into existing systems. The 74FST3251DTR2 is available in a TSSOP-16 package, which is inherently lead-free, aligning with modern environmental standards. This product is ideal for engineers seeking a reliable and efficient solution for multiplexing and demultiplexing signals in their designs.
