19-0270; Rev 0; 8/94 Precision, 16-Channel/Dual 8-Channel, High-Performance, CMOS Analog Multiplexers _______________General Description The MAX306/MAX307 precision, monolithic, CMOS analog multiplexers (muxes) offer low on-resistance (less than 100), which is matched to within 5 between channels and remains flat over the specified analog signal range (7 max). They also offer low leakage over temperature (I NO(OFF) less than 2.5nA at +85C) and fast switching speeds (tTRANS less than 250ns). The MAX306 is a single-ended 1-of-16 device, and the MAX307 is a differential 2-of-8 device. The MAX306/MAX307 are fabricated with Maxim's improved 44V silicon-gate process. Design improvements yield extremely low charge injection (less than 10pC) and guarantee electrostatic discharge (ESD) protection greater than 2000V. These muxes operate with a single +4.5V to +30V supply, or bipolar 4.5V to 20V supplies, while retaining TTL/CMOS-logic input compatibility and fast switching. CMOS inputs provide reduced input loading. These improved parts are plug-in upgrades for the industrystandard DG406, DG407, DG506A, and DG507A. ____________________________Features o Guaranteed On-Resistance Match Between Channels, <5 Max o Low On-Resistance, <100 Max o Guaranteed Flat On-Resistance over Specified Signal Range, 7 Max o Guaranteed Charge Injection, <10pC o INO(OFF) Leakage <2.5nA at +85C o ICOM(OFF) Leakage <20nA at +85C o ESD Protection >2000V o Plug-In Upgrade for Industry-Standard DG406/DG407/DG506A/DG507A o Single-Supply Operation (+4.5V to +30V) Bipolar-Supply Operation (4.5V to 20V) o Low Power Consumption, <1.25mW o Rail-to-Rail Signal Handling o TTL/CMOS-Logic Compatible MAX306/MAX307 ______________Ordering Information PART MAX306CPI MAX306CWI MAX306C/D MAX306EPI MAX306EWI MAX306EQI MAX306MJI TEMP.

Note 3: Guaranteed by design. Note 4: RON = RON(MAX) - RON(MIN). On-resistance match between channels and flatness are guaranteed only with specified voltages. Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured at the extremes of the specified analog signal range. Note 5: Leakage parameters are 100% tested at the maximum rated hot temperature and guaranteed by correlation at +25C. Note 6: Off isolation = 20log VCOM/VNO, where VCOM = output and VNO = input to off switch. 4 _______________________________________________________________________________________ Precision, 16-Channel/Dual 8-Channel, High-Performance, CMOS Analog Multiplexers __________________________________________Typical Operating Characteristics (TA = +25C, unless otherwise noted.)

The MAX306/MAX307 switches operate with 4.5V to 20V bipolar supplies or with a +4.5V to +30V single supply; connect V- to GND when operating with a single supply. Also, both device types can operate with unbalanced supplies such as +24V and -5V. The Typical Operating Characteristics graphs show typical on-resistance with 20V, 15V, 10V, and 5V supplies. (Switching times increase by a factor of two or more for operation at 5V.) signal range to 1V above V+ and 1V below V-, but low switch resistance and low leakage characteristics are unaffected. Device operation is unchanged, and the difference between V+ and V- should not exceed +44V. V+ NO COM Overvoltage Protection Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maximum ratings because stresses beyond the listed ratings may cause permanent damage to the devices. Always sequence V+ on first, then V-, followed by either the logic inputs, NO, or COM. If power-supply sequencing is not possible, add two small signal diodes in series with supply pins for overvoltage protection (Figure 1). Adding diodes reduces the analog Vg V- Figure 1.
