Product Overview: 74AC157SC from ON Semiconductor

The 74AC157SC is a high-performance, quad 2-input multiplexer designed by ON Semiconductor, a leading manufacturer in the semiconductor industry. This IC is part of the AC series, which is renowned for its high-speed operation and compatibility with TTL (Transistor-Transistor Logic) levels. The 74AC157SC is engineered to provide precise electrical characteristics and improved noise tolerance, making it an ideal choice for a wide range of digital applications.

Featuring four identical 2-input multiplexers, the 74AC157SC has the ability to select one of two inputs for each multiplexer using common select inputs and propagate that signal to the output. Each multiplexer has its own separate input-enable control which, when high, forces the corresponding output to a low state, thus providing additional flexibility in control operations.

The device is encapsulated in a compact SOIC-16 package, which is surface-mountable and suitable for automated assembly processes, making it a convenient choice for modern high-density electronic designs. The 74AC157SC operates over a broad voltage range of 2V to 6V and features a low quiescent current, which is beneficial for power-sensitive applications.

Key features of the 74AC157SC include:

• Logic Type: Quad 2-Input Multiplexer
• Operating Voltage Range: 2V to 6V
• High-Speed Operation: t_PD = 4.5 ns (max) at 5V
• Low Power Consumption: I_CC = 4 µA (max) at TA = 25°C
• Output Drive Capability: 24 mA at 5V
• Package Type: SOIC-16

The 74AC157SC is suitable for a variety of digital applications, including data routing, signal gating, and multiplexing. Its fast switching speed and compatibility with existing TTL logic systems make it a versatile component for designers looking to optimize their digital circuitry.
