The SGM4518 is an 8-channel, TTL/CMOS compatible analog multiplexer. It operates from +3.2V to +36V single power supply or ±3.2V to ±18V dual power supplies.
The SGM4518 features high voltage, low on-resistance and low distortion. The high performances make it very suitable for multiple applications, such as battery-operated equipment, audio and video signal routing, etc.
TTL/CMOS logic compatibility can be guaranteed when using a single +5V or dual ±5V power supplies because the logic thresholds of all digital inputs are between 0.8V and 2.4V.
The SGM4518 is available in Green SOIC-16, SSOP-16, TSSOP-16 and TQFN-3×3-16L packages. It operates over an operating temperature range of -40℃ to +125℃.
