Logic - Flip Flops

The MC10EP451FAR2G is a high-speed, low-power monolithic bipolar integrated circuit, specifically designed for use as a single-pole, double-throw (SPDT) switch. Eliminating the need for mechanical relays and discrete components, this device is ideal for applications in industrial and consumer apparatus that require switching between two outputs, such as SPDT relays, slide switch drivers, and general two-input logic functions.

The MC10EP451FAR2G is optimized for use in automotive and general-purpose applications running in less than 55°C ambient temperature. Although a wide range of voltage levels and operating frequencies are available, the MC10EP451FAR2G is primarily designed for operating at 12V DC, at 125kHz. The device is supplied in 8 different packages, allowing customers to choose the one that best suits their application’s needs.

Design and Working Principle

The MC10EP451FAR2G is a SPDT switch consisting of two pairs of complementary transistors, controlled by two transmission gates. The transistors pair is used to drive two loads, with each pair connected to one load. The two sets of transmission gates regulate the transistors’ current flow according to an input voltage.

The MC10EP451FAR2G is designed to operate within a given voltage range, ranging from 2V to 15V. The device is also able to handle currents up to 0.7A. The two transmission gates are controlled by two input signals: one for each of the SPDT switch’s outputs. When a high voltage is applied to either of the inputs, the corresponding transmission gate turns on, activating the corresponding pair of transistors and driving the respective output.

When no input signals are applied, both transmission gates are in the off-state, allowing the outputs to remain inactive. This principle also applies to the output levels: when no input signals are applied, both outputs are in the low state. When an input signal is applied, the corresponding output turns on. This allows the device to operate in a SPDT fashion.

Features and Advantages

The MC10EP451FAR2G is specifically designed to provide flexibility and improved performance in power switch applications. The device features a wide operating temperature range of -40°C to +125°C, ensuring reliable and robust operation under extreme operating conditions. In addition, the MC10EP451FAR2G is highly resistant to ESD, with a level of up to 14kV, providing reliable operation even in the most demanding applications.

The device is also designed for high-speed operation, with a typical switch times of up to 4ns. This feature makes the device an excellent choice for applications that require fast switching and response times, such as automotive electronics.

The device is also designed for low-power operations, with a typical power consumption of 3mW, allowing it to be used in energy-conscious applications. In addition, the MC10EP451FAR2G is offered in a wide range of packages, including SOT-23 and SOIC-8, allowing customers to choose the best package to suit their application’s needs.

Conclusion

The MC10EP451FAR2G is a high-speed, low-power and cost-effective SPDT switch, specifically designed for use in automotive and industrial applications. It features a wide operating temperature range, ESD protection, and low-power operation, making it an excellent choice for applications requiring reliable, fast, and cost-effective switch operation.
