MAX333A 19-0189 Rev 1 6/99 Precision, Quad, SPDT, CMOS Analog Switch General Description Features Upgraded Replacement for a DG211/DG212 Pair The MAX333A is a precision, quad, single-pole double- or Two DG403s throw (SPDT) analog switch. The four independent switches operate with bipolar supplies ranging from Low On Resistance < 17 Typical (35 Max) 4.5V to 20V, or with a single-ended supply between Guaranteed Matched On Resistance Between +10V and +30V. The MAX333A offers low on resistance Channels < 2 (less than 35), guaranteed to match within 2 between Guaranteed Flat On Resistance over Analog channels and to remain flat over the analog signal range Signal Range 3 Max (3 max). It also offers break-before-make switching Guaranteed Charge Injection < 10pC (10ns typical), with turn-off times less than 145ns and Guaranteed Off-Channel Leakage < 6nA at +85C turn-on times less than 175ns. The MAX333A is ideal for ESD Guaranteed > 2000V per Method 3015.7 portable operation since quiescent current runs less than 50A with all inputs high or low. Single-Supply Operation (+10V to +30V) Bipolar-Supply Operation (4.5V to 20V) This monolithic, quad switch is fabricated with Maxims TTL-/CMOS-Logic Compatibility new improved silicon-gate process. Design improvements guarantee extremely low charge injection (10pC), low Rail-to-Rail Analog Signal Handling Capability power consumption (3.75mW), and electrostatic discharge (ESD) greater than 2000V.
