产品概述

The MAX4620/MAX4630/MAX4640 low-voltage, high-ESD-protected, quad, single-pole/single-throw (SPST) analog switches are pin-compatible replacements for the industry-standard 74HC4066 analog switch. The normally open (NO) and normally closed (NC) pins are protected against ±15kV electrostatic discharge (ESD) without latchup or damage. Each switch can handle Rail-to-Rail analog signals. The 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 +2V to +12V single supply, making them ideal for use in battery-powered applications. The on-resistance is 70Ω max, matched between switches to 0.5Ω (typ), and flat (2Ω typ) over the specified signal range.

The MAX4620 has four NO switches, the MAX4630 has four NC switches, and the MAX4640 has two NO and two NC switches. These devices are available in 14-pin TSSOP, SO, and DIP packages.
