STMicroelectronics 74LVQ157TTR Multiplexer
The 74LVQ157TTR from STMicroelectronics is a high-performance, low-power, low-voltage quad 2-input multiplexer. This integrated circuit is designed for use in 3.3V systems where bandwidth, power consumption, and space are critical factors. It is particularly suitable for implementing logic functions, as well as for use in multiplexing and data routing applications.
The device features four identical 2-input multiplexers with common select and enable inputs. Each multiplexer has two data inputs (A and B), one output (Y), a common select input (S), and an enable input (G). The select input determines which of the two data inputs is connected to the output. When the enable input is 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.
Constructed with advanced silicon gate CMOS technology, the 74LVQ157TTR offers a robust combination of high speed and low power consumption. It can operate over a broad voltage range from 2V to 3.6V, with 5V tolerant inputs, which allows for interfacing with TTL logic levels. The device also features balanced propagation delays and output transition times, which contribute to its reliable and predictable performance characteristics.
Available in a TSSOP package, the 74LVQ157TTR is optimized for enhanced board-level density. It is a perfect choice for applications where space is at a premium, such as portable electronics, telecommunications, and computing systems. The multiplexer is also characterized for operation from -40°C to +85°C, ensuring that it can perform reliably in a wide range of environmental conditions.
In summary, the STMicroelectronics 74LVQ157TTR is a versatile and efficient solution for digital multiplexing needs. With its low-power consumption, high-speed operation, and small package size, it is an excellent choice for designers looking to optimize their high-performance 3.3V digital systems.
