19-0404; Rev. 1; 9/96 Precision, 16-Channel/Dual 8-Channel, Low-Voltage, CMOS Analog Multiplexers The MAX396/MAX397 low-voltage, CMOS analog multiplexers (muxes) offer low on-resistance (100Ω max), which is matched to within 6Ω between switches and remains flat over the specified signal range (10Ω max). They also offer low leakage over temperature (input off-leakage current less than 1nA at +85°C) and fast switching speeds (transition time less than 250ns). The MAX396 is a 16-channel device, and the MAX397 is a dual 8-channel device. The MAX396/MAX397 are fabricated with Maxim’s lowvoltage silicon-gate process. Design improvements yield extremely low charge injection (5pC max) and guarantee electrostatic-discharge (ESD) protection greater than 2000V per Method 3015.7 These muxes operate with a single +2.7V to +16V supply or with ±2.7V to ±8V dual supplies, while retaining CMOS-logic input compatibility and fast switching. The MAX396/MAX397 are pin compatible with the industrystandard MAX306/MAX307, DG406/DG407, and DG506A/DG507A. ________________________Applications Sample-and-Hold Circuits Avionics Battery-Operated Equipment Low-Voltage Data Acquisition Systems Automatic Test Equipment Communications Systems Audio Signal Routing Industrial Process Control ____________________________Features ♦ Pin Compatible with MAX306/MAX307, DG406/DG407, DG506A/DG507A ♦ Single-Supply Operation (+2.7V to +16V) Dual-Supply Operation (±2.7V to ±8V) ♦ Low On-Resistance (100Ω max) ♦ Guaranteed RON Match Between Channels (6Ω max) ♦ Guaranteed RON Flatness over Specified Signal Range (10Ω max) ♦ Guaranteed Low Charge Injection (5pC max) ♦ Input Off-Leakage Current < 1nA at +85°C ♦ Output Off-Leakage Current < 2.5nA at +85°C ♦ Low Power Consumption < 10µW ♦ TTL/CMOS Compatible ______________Ordering Information TEMP.

Note 6: Leakage parameters are 100% tested at maximum rated hot operating temperature, and guaranteed by correlation at +25°C.

The MAX396/MAX397 multiplexers (muxes) operate with ±3V to ±8V bipolar supplies or with a +3V to +15V single supply. Connect V- to GND when operating with a single supply. Both devices can also operate with unbalanced supplies, such as +10V and -5V. The Typical Operating Characteristics graphs show typical onresistance with ±3V, ±5V, +3V, and +5V supplies. (Switching times increase by a factor of two or more for operation at 5V or below.) These muxes operate with a single supply as low as 1V, although on-resistance and switching times become extremely high. Performance is not guaranteed below 2.7V. This is useful information only because it assures proper switch state while power supplies ramp up or down slowly. is not possible, add two small-signal diodes (D1, D2) in series with supply pins for overvoltage protection (Figure 1). Adding diodes reduces the analog-signal range to one diode drop below V+ and one diode drop above V-, but does not affect the devices’ low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between V+ and V- should not exceed 17V. These protection diodes are not recommended when using a single supply. +5V D1 V+ MAX396 MAX397 * * 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 can cause permanent damage to the devices. Always sequence V+ on first, then V-, followed by the logic inputs, NO, or COM. If power-supply sequencing VD2 -5V *INTERNAL PROTECTION DIODES Figure 1.
