1 9-79; Rev ; /07 Low-Voltage, Quad, SPST General Description The MAX0/MAX/MAX are quad, low-voltage, single-pole/single-throw (SPST) analog switches. On-resistance (00Ω, max) is matched between switches to Ω, max and is flat (Ω, max) over the specified signal range. Each switch handles to analog signal levels. Maximum off-leakage current is only na at and na at T A = +8 C. The MAX0 has four normally open (NO) switches, and the MAX has four normally closed (NC) switches. The MAX has two NO switches and two NC switches. These CMOS switches operate from a single +V to +V supply. All digital inputs have +0.8V and +.V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +V supply.

MAX0/MAX/MAX Applications Information Power-Supply Sequencing and Overvoltage Protection Do not exceed the absolute maximum ratings, because stresses beyond the listed ratings may cause permanent damage to the devices. Proper power-supply sequencing is recommended for all CMOS devices. Always apply before applying analog signals or logic inputs, especially if the analog or logic signals are not current limited. If this sequencing is not possible, and if the analog or logic inputs are not current limited to 0mA, add a small-signal diode (D) as shown in Figure. If the analog signal can dip below, add D. Adding protection diodes reduces the analog signal range to a diode drop (about 0.7V) below (for D), and to a diode drop above ground (for D). Leakage is unaffected by adding the diodes. On-resistance increases by a small amount at low supply voltages. Maximum supply voltage () must not exceed V. Adding protection diodes causes the logic thresholds to be shifted relative to the power-supply rails. This can be V g NO_ POSITIVE SUPPLY MAX0 MAX MAX COM_ Figure. Overvoltage Protection Using Two External Blocking Diodes significant when low supply voltages (+V or less) are used. With a +V supply, TTL compatibility is not guaranteed when protection diodes are added. Driving IN and all the way to the supply rails (i.e., to a diode drop higher than the pin, or to a diode drop lower than the pin) is always acceptable. 7

8 MAX0/MAX/MAX Protection diodes D and D also protect against some overvoltage situations. With Figure s circuit, if the supply voltage is below the absolute maximum rating, and if a fault voltage up to the absolute maximum rating is applied to an analog signal pin, no damage will result. Operating Considerations for High-Voltage Supply The MAX0/MAX/MAX are pin-compatible with the industry-standard 7HC0 and the MAX0, and are optimized for +V single-supply operation. The MAX0 family is capable of +V MAX0 MAX MAX V COM _ SWITCH INPUT LOGIC INPUT COM_ IN_ NO_, NC_ R L 00Ω SWITCH OUTPUT C L pf V OUT single-supply operation with some precautions. The absolute maximum rating for is +.V (referenced to ). When operating near this region, bypass with a minimum 0.µF capacitor to ground as close to the IC as possible. Caution: The absolute maximum to V- differential voltage is.0v. Typical ±V or V supplies with ±0% tolerances can be as high as.v. This voltage can damage the MAX0/MAX/MAX. Even ±% tolerance supplies may have overshoot or noise spikes that exceed.0v.
