These switches exhibit low leakage current (0.1nA) and consume less than 0.5nW (typ) of quiescent power, making them ideal for batterypowered applications. When powered from a +3V supply, these switches feature 50Ω (max) on-resistance (RON) with 3.5Ω (max) matching between channels, and 9Ω (max) flatness over the specified signal range.

Limit forward-diode current to maximum current rating. Note 2: This device is constructed using a unique set of packaging techniques that impose a limit on the thermal profile the device can be exposed to during board level solder attach and rework. This limit permits only the use of the solder profiles recommended in the industry-standard specification, JEDEC 020A, paragraph 7.6, Table 3 for IR/VPR and Convection reflow. Preheating is required. Hand or wave soldering is not allowed. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The absolute maximum rating for V+ is +12V (referenced to GND). When operating near this region, bypass V+ with a minimum 0.1µF capacitor to ground as close to the IC as possible. Logic Levels The MAX4731/MAX4732/MAX4733 are TTL compatible when powered from a single +5V supply. When powered from other supply voltages, the logic inputs should Analog-Switch Common Terminal be driven rail-to-rail. For example, with a +11V supply, IN1 and IN2 should be driven low to 0V and high to 11V. With a +3.3V supply, IN1 and IN2 should be driven low to 0V and high to 3.3V. Driving IN1 and IN2 railto-rail minimizes power consumption. Analog Signal Levels Analog signals that range over the entire supply voltage (GND to V+) pass with very little change in RON (see Typical Operating Characteristics). The bidirectional switches allow NO_, NC_, and COM_ connections to be used as either inputs or outputs. _______________________________________________________________________________________ 7 MAX4731/MAX4732/MAX4733 Typical Operating Characteristics (continued) (TA = +25°C, unless otherwise noted.) MAX4731/MAX4732/MAX4733 50Ω Dual SPST Analog Switches in UCSP Power-Supply Sequencing and Overvoltage Protection CAUTION: Do not exceed the absolute maximum ratings. Stresses beyond the listed ratings can cause permanent damage to the devices. Proper power-supply sequencing is recommended for all CMOS devices. Always apply V+ before applying analog signals, especially if the analog signal is not current limited. If this sequencing is not possible, and if the analog inputs are not current limited to <20mA, add a small-signal diode, D1, as shown in Figure 1. If the analog signal can dip below GND, add D2. Adding protection diodes reduces the analog signal range to a diode drop (about 0.7V) below V+ (for D1), and to a diode drop above ground (for D2). Leakage is unaffected by adding the diodes. On-resistance increases slightly at low supply voltages. Maximum supply voltage (V+) must not exceed +11V. Adding protection diodes causes the logic thresholds to be shifted relative to the power-supply rails. The most significant shift occurs when using low supply voltages (+5V or less). With a +5V supply, TTL compatibility is not guaranteed when protection diodes are added. Driving IN1 and IN2 all the way to the supply rails (i.e., to a diode drop higher than the V+ pin, or to a diode drop lower than the GND pin) is always acceptable. Protection diodes D1 and D2 also protect against some overvoltage situations. Using the circuit in Figure 1, no damage results if the supply voltage is below the absolute maximum rating (+12V) and if a fault voltage up to the absolute maximum rating (V+ + 0.3V) is applied to an analog signal terminal. UCSP Reliability The chip-scale package (UCSP) represents a unique package that greatly reduces board space compared to other packages. UCSP reliability is integrally linked to the user’s assembly methods, circuit board material, and usage environment. The user should closely review these areas when considering a UCSP. Performance through Operation Life Test and Moisture Resistance is equal to conventional package technology as the wafer-fabrication process primarily determines it. However, this form factor may not perform equally to a packaged product through traditional mechanical reliability tests. Mechanical stress performance is a greater consideration for a UCSP. UCSP solder joint contact integrity must be considered since the package is attached through direct solder contact to the user’s PC board. Testing done to characterize the UCSP reliability performance shows that it is capable of performing reliably through environmental stresses. Results of environmental stress test and additional usage data and recommendations are detailed in the UCSP application note, which can be found on Maxim’s website at www.maxim-ic.com.
