ON Semiconductor 74FST3257DR2G Quad 2:1 Multiplexer/Demultiplexer

The 74FST3257DR2G from ON Semiconductor is a high-performance, quad 2:1 multiplexer/demultiplexer designed for applications requiring high-speed switching and signal routing. This integrated circuit is part of the advanced FST series, offering a significant upgrade in speed and performance over traditional multiplexer/demultiplexer devices.

Constructed with Silicon Gate CMOS technology, it boasts a low On Resistance of 5Ω (typical) at a 4.5V supply voltage. This ensures minimal signal distortion and provides excellent signal integrity. The device operates with a supply voltage ranging from 4.5V to 5.5V, making it versatile for various digital logic levels and compatible with TTL logic families.

Each multiplexer/demultiplexer in the 74FST3257DR2G has two select inputs (S0 and S1) and an enable input (E) which can be used to turn the device on or off. When enabled, the device connects one of the two data inputs to the output, depending on the state of the select inputs. This feature is critical for applications that require data routing, such as signal switching in communication devices, data buses in computing, and video/audio signal processing.

The 74FST3257DR2G offers a low propagation delay, typically 250ps, which is critical for maintaining high-speed data transmission without significant time lag. This makes it an excellent choice for high-frequency applications where timing is crucial.

Moreover, the device comes in a space-saving SOIC-16 package, which is ideal for compact PCB layouts where space is at a premium. Its operating temperature range from -40°C to +85°C ensures reliable performance in a wide range of environmental conditions.
