ON Semiconductor 74AC157PC: Quad 2-Input Multiplexer

The 74AC157PC is a high-speed Quad 2-Input Multiplexer designed by ON Semiconductor that offers a perfect solution for selecting and routing digital signals within your circuit. This multiplexer, commonly referred to as a MUX, is a critical component in digital and communication systems, where it efficiently manages multiple inputs, directing them to a single output line.

Manufactured with advanced CMOS technology, the 74AC157PC provides users with a significant advantage in terms of speed and power consumption. The device operates over a wide voltage range from 2V to 6V, making it versatile for various applications. Its low power consumption is ideal for battery-operated and portable devices, ensuring longevity and reliability.

The 74AC157PC features four individual 2-input multiplexers with common select inputs and an enable input. Each multiplexer has two data inputs (A and B), one output (Y), and a select input (S). The select input determines which of the data inputs is connected to the output. When the enable input (G) is low, the multiplexers are active, and the data from the selected inputs is passed to the outputs. If the enable input is high, all outputs are forced to a high impedance state, effectively disconnecting the multiplexer from the circuit.

This ON Semiconductor product is packaged in a 16-pin DIP (Dual In-line Package), which allows for easy integration into a wide range of electronic systems. The 74AC157PC is characterized for operation from -40°C to 85°C, ensuring stable performance in extreme conditions. Its fast switching speeds and low propagation delay are essential for high-performance computing and critical data processing tasks.

Whether used in data multiplexing, signal gating, or as a function generator, the 74AC157PC from ON Semiconductor is an excellent choice for designers looking for a reliable and efficient way to manage multiple digital inputs. Its robust design and operational flexibility make it a go-to component in both simple and complex digital circuits.
