STMicroelectronics 74LVQ157MTR Multiplexer

The 74LVQ157MTR from STMicroelectronics is a high-performance, low-power, quad 2-input multiplexer that operates from a 2.0 to 3.6V power supply. This multiplexer is part of the LVQ family, which is known for its low-voltage operation and high-speed interfacing capabilities. The 74LVQ157MTR is designed for use in applications where space is at a premium and low power consumption is crucial.

This device features four individual 2-input multiplexers with common select inputs and individual enable inputs. The select inputs determine which of the inputs (A or B) is connected to the corresponding output. When the enable input is low, the respective multiplexer is operational; when high, the multiplexer is disabled, and the output is in a high-impedance state, allowing for the connection of multiple outputs to a common bus without interference.

The 74LVQ157MTR offers high-speed performance with a typical propagation delay of only 4.5 ns when operating at 3.3V, making it suitable for high-speed data routing applications. Its low power dissipation and quiet operation are due to the low power Schottky technology, which also contributes to its robustness against noise and interference.

STMicroelectronics has packaged the 74LVQ157MTR in a TSSOP (Thin Shrink Small Outline Package) format, which is ideal for space-constrained applications. The TSSOP package also provides improved thermal performance and reduced inductance compared to traditional packaging options, ensuring reliable operation even under varying environmental conditions.

The 74LVQ157MTR is fully specified for hot insertion and withdrawal, which means it can be integrated into live systems without the need to power down. This feature is particularly valuable in systems that require high availability and minimal downtime. With its wide operating temperature range from -40°C to +85°C, the 74LVQ157MTR is suitable for industrial and commercial applications, including telecommunications, computing, and data storage systems.

Overall, the STMicroelectronics 74LVQ157MTR is a versatile and efficient solution for designers looking to optimize their multiplexing needs in their digital systems, with the reliability and performance that come with the STMicroelectronics brand.
