MAX4577

±15kV ESD保护、低电压、双路、SPST、CMOS模拟开关


点击查看特定型号的库存状况。

说明

The MAX4575/MAX4576/MAX4577 are low-voltage, high electrostatic discharge (ESD)-protected, dual single-pole/single-throw (SPST) analog switches. The normally closed (NC) and normally open (NO) pins are protected against ±15kV ESD without latchup or damage. Each switch can handle rail-to-rail analog signals. Off-leakage current is 0.5nA at +25°C. These analog switches are suitable for low-distortion audio applications and are the preferred solution over mechanical relays in automated test equipment or applications where current switching is required. They have low power requirements (0.5µW), require less board space, and are more reliable than mechanical relays. Each device is controlled by TTL/CMOS input voltage levels and is bilateral.

These switches feature guaranteed operation from a single supply of +2V to +12V, making them ideal for use in battery-powered applications. On-resistance is 70Ω (max), matched between switches to 0.5Ω (typ) and flat (2Ω typ) over the specified signal range.

The MAX4575 has two NO switches, the MAX4576 has two NC switches, and the MAX4577 has one NO and one NC switch. These devices are available in 8-pin µMAX® and SO packages.
