ON Semiconductor 74VHC157SJ Quad 2-Input Multiplexer

The ON Semiconductor 74VHC157SJ is a high-performance CMOS quad 2-input multiplexer that combines the best of both speed and power efficiency. This versatile integrated circuit is designed to operate at 2V to 5.5V, making it suitable for a wide range of applications in the consumer, automotive, and telecommunications industries. The 74VHC157SJ is part of ON Semiconductor's VHC family, known for its robustness and reliability.

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

The 74VHC157SJ boasts a high-speed propagation delay with a balanced drive that provides significant advantages in power consumption and noise reduction. Its low-power dissipation and high noise immunity are characteristics of CMOS technology, making it an excellent choice for battery-operated devices and other power-sensitive applications.

This multiplexer is offered in a surface-mount, 16-pin SOIC package, ensuring a compact footprint on printed circuit boards. Its pin configuration is industry-standard, which simplifies the design process and allows for easy integration into existing systems.

The 74VHC157SJ is also characterized by its latch-up performance that exceeds 300mA, which conforms to the JESD 17 standard. This feature ensures that the device is protected against the sudden application of excessive current, enhancing its robustness and durability in harsh electrical environments.

With its combination of high-speed operation, low power consumption, and compact size, the ON Semiconductor 74VHC157SJ is an excellent choice for designers looking to optimize their multiplexing applications. Whether you're developing sophisticated communication systems or designing consumer electronics, this multiplexer from ON Semiconductor can help you achieve a reliable and efficient performance.
