ON Semiconductor MM74HC157SJX Multiplexer
The ON Semiconductor MM74HC157SJX is a high-performance, quad 2-input multiplexer that seamlessly integrates into a wide array of digital systems. This device is designed to work with a 2V to 6V operating voltage range, making it suitable for various applications, from battery-operated devices to industrial control systems.
Constructed with advanced silicon-gate CMOS technology, the MM74HC157SJX offers the dual benefit of high-speed operation similar to LSTTL combined with the low power consumption characteristic of CMOS integrated circuits. This makes it an excellent choice for systems where energy efficiency and speed are both critical factors.
The MM74HC157SJX features four individual 2-input multiplexers with common select and enable inputs. Each multiplexer has two data inputs (A and B), one output (Y), one select input, and an active LOW enable input. The select input determines which of the data inputs A or B is propagated to the output Y when the enable input is at a logic low level. If the enable input is at a logic high level, the outputs are forced to a high impedance state, allowing for the possibility to connect multiple outputs to a common bus without the risk of bus contention.
This device is available in a surface-mount package, specifically the SJX suffix, which denotes a Thin Shrink Small Outline Package (TSSOP) with 16 leads. This compact form factor is ideal for space-constrained applications and provides for high-density mounting on PCBs.
ON Semiconductor's MM74HC157SJX is characterized for operation from -55°C to +125°C, ensuring reliable performance across a broad range of environmental conditions. This robustness makes it suitable for use in automotive, industrial, and military applications where extreme temperatures are a common challenge.
In summary, the MM74HC157SJX from ON Semiconductor is a versatile and efficient solution for routing digital signals in complex electronic systems. Its high-speed operation, low power consumption, and robust design make it a valuable component for designers looking to optimize their digital multiplexing applications.
