MAX323/MAX324/MAX325 19-0347 Rev 1 10/97 Precision, Single-Supply, SPST Analog Switches General Description Features The MAX323/MAX324/MAX325 are precision, dual, Low On-Resistance (R ), 60 max (33 typ) ON SPST analog switches. They are single-supply devices R Matching Between Channels <2 ON designed to operate from +2.7V to +16V. The MAX323 R Flatness <6 Max ON has two normally open (NO) switches, and the MAX324 has two normally closed (NC) switches. The MAX325 Guaranteed Charge Injection <5pC has one NO and one NC switch. Low power consump- Single-Supply Operation (+2.7V to +16V) tion (5W) makes these parts ideal for battery-powered Low Power Consumption, <5W equipment. These switches offer low leakage currents (100pA max) and fast switching speeds (t = 150ns Low Leakage Current Over Temperature, ON max, t = 100ns max). <2.5nA at +85C OFF When powered from a 5V supply, the MAX323 series Fast Switching: t <150ns, t <100ns ON OFF offers 2 max matching between channels, 60 max Guaranteed Break-Before-Make (MAX325 only) on-resistance, and 6 max R flatness. ON TTL/CMOS Logic Compatible These switches also offer 5pC max charge injection, and a minimum of 2000V ESD per Method 3015.7.

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.
