NC7WB3125K8X Logic-Signal Switches, Multiplexers, Decoders

The NC7WB3125K8X are silicon logic-signal switches, multiplexers, and decoders specifically designed to replace mechanical switches in a variety of applications. The switches are part of the high speed digital logic family of devices from Lattice, offering high performance, low power, and easy connection in a space-saving package.

Features

• 2:1 Multiplexer/Demultiplexer
• Single-ended or differential keying
• High-speed switching of up to 20 Mbps
• High-impedance input/output
• TTL compatible inputs/outputs
• Small 8-pin SSOP package size

Applications

• Automotive electronics
• Avionics
• Consumer electronics
• Communication systems

Working Principle

The NC7WB3125K8X provides single-channel logic-signal switching with high impedance input/outputs. The device is a differential switch so the input/output signals are always in phase. It can be used to switch either single-ended voltage levels or differential signals between two independent paths.

The main IC consists of two switching stages, an input stage and an output stage. The input stage is controlled by an enable/disable input, which determines if the switch is closed or open. The output stage is controlled by a series of output enable/disable signals which determine if the output is enabled or disabled.

The NC7WB3125K8X also provides a number of protection circuits, such as input protection and latch-up protection. Input protection ensures the device can be used in high ESD environments; the latch-up protection ensures the device will not latch up due to the ESD.

Conclusion

The NC7WB3125K8X is a silicon logic-signal switch, multiplexer, and decoder. It is specifically designed for high speed applications such as automotive electronics, avionics, consumer electronics, and communication systems. The device can switch both single-ended and differential signals and has many built-in protection circuits for high ESD environments.
