ON Semiconductor MC74HC157ANG Quadruple 2-Input Multiplexer
The MC74HC157ANG from ON Semiconductor is a high-performance, silicon-gate CMOS quadruple 2-input multiplexer with a common select input. This integrated circuit is designed to be a versatile component for use in digital systems where low power consumption and high noise immunity are essential. It is capable of operating at the same high speeds as LSTTL parts while maintaining the CMOS low power dissipation.
This multiplexer device features four pairs of inputs, each of which can be selected by the common select input. The binary control input dictates which of the two inputs for each pair is propagated to the output. When the enable input is high, all the outputs are forced to a low state, regardless of the other inputs, providing an additional control level.
The MC74HC157ANG is characterized for operation from -55°C to +125°C, making it suitable for a wide range of applications, from automotive to industrial environments. Its pin configuration is designed for easy PCB layout, with all inputs and outputs placed to facilitate routing and minimize the possibility of cross-talk.
Key features of the MC74HC157ANG include:
- High noise immunity characteristic of CMOS devices
- Low power consumption, ideal for battery-operated and low-power systems
- Wide operating voltage range of 2V to 6V
- Output drive capability of 10 LSTTL loads, allowing for easy interfacing with other logic families
- In compliance with the JEDEC standard no. 7A requirements
- Chip complexity: 132 FETs or 33 equivalent gates
The MC74HC157ANG is available in a 16-lead PDIP package, ensuring compatibility with through-hole PCB assembly processes. Its robust design and ON Semiconductor's commitment to quality make it a reliable choice for designers looking to implement multiplexing functions in their digital logic circuits.
Overall, the MC74HC157ANG is a practical solution for applications requiring the selection of multiple signal sources to a single output path, offering high performance and reliability in a wide range of operating conditions.
