Low-Voltage, Quad, SPDT, MAX394 CMOS Analog Switch General Description Features The MAX394 is a precision, low-voltage, quad, single- Low On-Resistance, < 17 Typical (35 max) pole/double-throw (SPDT) analog switch. The four inde- Guaranteed Matched On-Resistance Between pendent switches operate with bipolar supplies ranging Channels, < 2 from 2.7V to 8V, or with a single supply of +2.7V to Guaranteed Flat On-Resistance over Analog +15V. The MAX394 offers low on-resistance (less than Signal Range, 4 Max 35), guaranteed to match within 2 between channels Guaranteed Charge Injection < 10pC and to remain flat over the analog signal range (4 Guaranteed Off-Channel Leakage < 2.5nA at +85C max). It also offers break-before-make switching (10ns ESD Guaranteed > 2000V per Method 3015.7 typical), with turn-off times less than 75ns and turn-on Single-Supply Operation (+2.7V to +15V) times less than 130ns. The MAX394 is ideal for portable operation since quiescent current runs less than 1A with Bipolar-Supply Operation (2.7V to 8V) all inputs high or low. TTL/CMOS-Logic Compatibility This monolithic, quad switch is fabricated with Maxims Rail-to-Rail Analog Signal Handling Capability low-voltage silicon-gate process. Design improvements Pin Compatible with MAX333, MAX333A guarantee extremely low charge injection (10pC), low power consumption (10W), and electrostatic discharge Ordering Information (ESD) greater than 2000V.

Limit forward diode current to maximum current rating. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
