9-027; Rev 2; 8/02 Precision, 8-Channel/Dual 4-Channel, General Description The / precision, monolithic, CMOS analog multiplexers (muxes) offer low on-resistance (less than 0Ω), which is matched to within 5Ω between channels and remai flat over the specified analog signal range (7Ω max). They also offer low leakage over temperature (NO-off leakage current less than 5nA at +85 C) and fast switching speeds (traition time less than 250). The is a single-ended -of-8 device, and the is a differential 2-of-4 device. The / are fabricated with Maxim s improved 44V silicon-gate process. Design improvements yield extremely low charge injection (less than pc) and guarantee electrostatic discharge protection greater than 200. These muxes operate with a single +5V to +3 supply or bipolar ±5V to ±2 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 DG408, DG409, DG508A, and DG509A.

The / switches operate with ±5V to ±2 bipolar supplies or with a +5V to +3 single supply. Connect to GND when operating with a single supply. Both device types can also operate with unbalanced supplies, such as +24V and -5V. The Typical Operating Characteristics graphs show typical on-resistance with 2, 5V, V, and 5V supplies. (Switching times increase by a factor of two or more for operation at 5V.) 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 on first, then, followed by the logic inputs, NO, or. If power-supply sequencing is not possible, add two small signal diodes in series with supply pi for overvoltage protection (Figure ). Adding diodes reduces the analog signal range to V below and V 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 +44V. V g NO Figure. Overvoltage Protection Using External Blocking Diodes 6
