/ Precision, 6-Channel/Dual 8-Channel, General Description The / low-voltage, CMOS analog multiplexers (muxes) offer low on-resistance (Ω max), which is matched to within 6Ω between switches and remains flat over the specified signal range (Ω max). They also offer low leakage over temperature (input off-leakage current less than na at +8 C) and fast switching speeds (transition time less than 2ns). The is a 6-channel device, and the is a dual, 8-channel device. The / are fabricated with Maxim s lowvoltage silicon-gate process. Design improvements yield extremely low charge injection (pc max) and guarantee electrostatic-discharge (ESD) protection greater than 2V per Method 3.7 These muxes operate with a single +2.7V to +6V supply or with ±2.7V to ±8V dual supplies, while retaining CMOSlogic input compatibility and fast switching. The / are pin compatible with the industry standard MAX36/MAX37, DG46/DG47, and DG6A/DG7A.

/ Precision, 6-Channel/Dual 8-Channel, Applications Information Operation with Supply Voltages Other than ±V Using supply voltages less than ±V reduces the analog signal range. The / multiplexers (muxes) operate with ±3V to ±8V bipolar supplies or with a to single supply. Connect to GND when operating with a single supply. Both devices can also operate with unbalanced supplies, such as +V and. The Typical Operating Characteristics graphs show typical on-resistance with ±3V, ±V,, and supplies. These muxes operate with a single supply as low as V, 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. 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 on first, then, followed by the logic inputs, NO, or. If power-supply sequencing is not possible, add two smallsignal diodes (D, D2) in series with supply pins for overvoltage protection (Figure ). Adding diodes reduces the analog-signal range to one diode drop below and one diode drop above, but does not affect the devices low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between and should not exceed 7V. These protection diodes are not recommended when using a single supply.
