Logic-signal switches, multiplexers, and decoders are important components of both digital and analog circuits. The SN74CBT3306CDR is a CMOS analog multiplexer/demultiplexer integrated circuit (IC) for single-pole/double-throw (SPDT) operation that can address a wide range of applications. Here, we will discuss its application field and working principle in detail.

Application Field

The SN74CBT3306CDR is widely used in high-performance electronic systems, such as video switching, instrumentation, medical systems and avionics, that require low on-resistance, low power consumption and linearity. It has a power supply range (VCC) of 2.375V to 5.25V. The SN74CBT3306CDR is considered an automobile-grade part and offers a guaranteed s-parameter performance over the full automotive temperature range (-40°C to +125°C). To sum up, it has the following features:

• Low on-resistance: 1.7Ω typ.
• 3.3V single supply operation
• Power supply tracking for A/B ports available
• Low power consumption: 0.35 mW typ.
• Wide input common-mode range: ±1.25V to VCC-1.25V
• Matches A/B port low on-resistance to 25µA
• Matches input offsets and input bias currents

The SN74CBT3306CDR is best suited for harsh environment applications, where it can efficiently operate under low power, high temperature, and high reliability conditions. In addition, the device also supports hot swap functionality, which means it can be added or removed from an operational system without powering down. It is also compatible with standard logic families, such as TTL and CMOS, so it can easily be used in various circuit designs.

Working Principle

The SN74CBT3306CDR consists of two SPDT switches, each having both control and active sides, across which a signal current can be sent. The control side is used to alternate the signal current between the two active sides of the switch, and consists of two control terminals, C1 and C2. When C1 is high, the signal current is sent to A, and when C2 is high, the signal current is sent to B. If both C1 and C2 inputs are low, then no current is passed through the SPDT switch.

The active sides of the SPDT switch are the terminals A and B, which are connected to A/B tracks. The A/B tracks consist of a 1kΩ resistor in series and in parallel with a 1:1 matched resistor. The A/B tracks can accept input signals ranging from ±10V to 0V. The A/B track matches the low on-resistance of the SPDT switch, which is typically 1.7Ω.

The SN74CBT3306CDR can be used with a wide range of digital and analog signals, such as video and audio signals, as the device offers low on-resistance and high linearity performance. Additionally, the low power consumption of the device ensures that it will not cause any degradation of the performance of the system.

Conclusion

The SN74CBT3306CDR is a CMOS analog multiplexer/demultiplexer that can be incorporated into a wide range of electronic systems to switch, multiplex, and decode digital and analog signals. It has a wide range of features such as low on-resistance and low power consumption, making it a viable choice for automotive, instrumentation, and medical applications. The operation of the device is quite easy to understand as well, since it consists of two SPDT switches.
