The 74CBTLV3253BQ115 is a high-performance, low-voltage dual 1-of-4 multiplexer/demultiplexer manufactured by NXP Semiconductors. This integrated circuit (IC) is designed for use in applications that require routing of digital signals up to 200 MHz and is particularly suited for server, networking, and telecommunications equipment.

The device features two individual 4-channel multiplexers/demultiplexers with common select inputs and separate enable inputs. It operates over a wide voltage range of 2.3V to 3.6V, which allows it to interface with both 3.3V and 2.5V logic levels, providing a versatile solution for mixed-voltage system environments. The 74CBTLV3253BQ115 is characterized for operation from -40°C to +85°C, ensuring reliable performance across various operating conditions.

With its low on-state resistance, the 74CBTLV3253BQ115 offers minimal signal distortion and supports bidirectional data flow with near-zero propagation delay. This feature makes it an excellent choice for signal routing applications, where maintaining signal integrity is crucial. The quick switch capability ensures that data can be routed with high speed, which is essential for modern high-performance systems.

The device is housed in a compact DHVQFN20 package, which is space-saving and ideal for densely populated PCBs. The leadless package design also helps in achieving better thermal performance and reduced inductance, which is beneficial for high-frequency operation.
