The SN74AHC158NSR, from Texas Instruments, is a high-performance, quadruple 2-line to 1-line data selector/multiplexer that operates from a wide range of 2 V to 5.5 V. This integrated circuit is designed to provide high-speed, low-power operation, making it suitable for a variety of digital applications. Encased in an SOP (Small Outline Package), the SN74AHC158NSR is designed for surface-mount technology, providing a compact and efficient solution for space-constrained applications.

The device features four multiplexer units, each with two inputs and one output, along with two common select inputs and an output enable input. The select inputs determine which of the data inputs are allowed to pass through to the output. When the output enable input is low, the outputs are active and reflect the selected inputs. If the output enable is high, the outputs are disabled and enter a high-impedance state, which helps in reducing power consumption and allows for the multiplexing of different signals without interference.

With its low on-state resistance and minimal propagation delay, the SN74AHC158NSR is optimized for high-speed signal switching. The device is also characterized for operation from -40°C to 85°C, making it reliable for industrial temperature ranges. Additionally, the SN74AHC158NSR supports the bus-hold feature on the data inputs, which eliminates the need for external pull-up or pull-down resistors and helps in maintaining the last known state during periods of high-impedance.

The SN74AHC158NSR is RoHS compliant, ensuring that it meets current environmental standards by avoiding the use of hazardous substances. Texas Instruments' commitment to quality and performance is evident in this product, which is rigorously tested to meet stringent industry specifications. Whether used in digital signal routing, data selection, or as a control interface, the SN74AHC158NSR provides a reliable and efficient solution for your digital switching needs.
