ISL84524, ISL84525 Data Sheet February 24, 2012 Low-Voltage, Single Supply, 4 to 1 Multiplexer and DPDT Analog Switches The Intersil ISL84524 and ISL84525 devices are precision, bidirectional, analog switches configured as a 4 channel multiplexer/demultiplexer (ISL84524) and a double pole/double throw (DPDT) switch (ISL84525) designed to operate from a single +2V to +12V supply. Both have an inhibit pin to simultaneously open all signal paths. ON resistance is 200Ω with a +5V supply and 500Ω with a +3V supply. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 1nA at +25°C or 25nA at +85°C. All digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS logic compatibility when using a single +5V supply. The ISL84524 is a 4 to 1 multiplexer device. The ISL84525 is a DPDT, which is perfect for use in 2-to-1 multiplexer applications. Table 1 summarizes the performance of this family. For higher performance, see the ISL43640 and ISL43410 data sheets. TABLE 1.

CAPACITANCE TEST CIRCUIT FN6042.3 February 24, 2012 ISL84524, ISL84525 Detailed Description Power-Supply Considerations The ISL84524 and ISL84525 operate from a single 2V to 12V supply with low on-resistance and high speed operation. The devices are especially well suited to portable battery powered equipment thanks to the low operating supply voltage (2.7V), low power consumption (3µW), low leakage currents (25nA max), and the tiny MSOP packaging. High frequency applications also benefit from the wide bandwidth, and the very high off isolation (75dB) and crosstalk rejection (-85dB). The ISL8452X construction is typical of most CMOS analog switches, except that they have only two supply pins: V+ and GND. V+ and GND drive the internal CMOS switches and set their analog voltage limits. Unlike switches with a 13V maximum supply voltage, the ISL8452X 15V maximum supply voltage provides plenty of room for the 10% tolerance of 12V supplies, as well as room for overshoot and noise spikes. Supply Sequencing and Overvoltage Protection With any CMOS device, proper power supply sequencing is required to protect the device from excessive input currents which might permanently damage the IC. All I/O pins contain ESD protection diodes from the pin to V+ and to GND (see Figure 8). To prevent forward biasing these diodes, V+ must be applied before any input signals, and the input signal voltages must remain between V+ and GND. If these conditions cannot be guaranteed, then precautions must be implemented to prohibit the current and voltage at the logic pin and signal pins from exceeding the maximum ratings of the switch. The following two methods can be used to provide additional protection to limit the current in the event that the voltage at a signal pin or logic pin goes below ground or above the V+ rail. Logic inputs can be protected by adding a 1kΩ resistor in series with the logic input (see Figure 8). The resistor limits the input current below the threshold that produces permanent damage, and the sub-microamp input current produces an insignificant voltage drop during normal operation. This method is not acceptable for the signal path inputs. Adding a series resistor to the switch input defeats the purpose of using a low RON switch. Connecting Schottky diodes to the signal pins (as shown in Figure 8) will shunt the fault current to the supply or to ground thereby protecting the switch. These Schottky diodes must be sized to handle the expected fault current. OPTIONAL SCHOTTKY DIODE V+ OPTIONAL PROTECTION RESISTOR INH ADDX VNX VCOM GND OPTIONAL SCHOTTKY DIODE The minimum recommended supply voltage is 2V. It is important to note that the input signal range, switching times, and on-resistance degrade at lower supply voltages. Refer to the Electrical Specification tables (starting on page 3) and Typical Performance Curves (starting on page 10) for details. V+ and GND also power the internal logic and level shifters. The level shifters convert the input logic levels to switched V+ and GND signals to drive the analog switch gate terminals. This family of switches cannot be operated with bipolar supplies, because the input switching point becomes negative in this configuration. Logic-Level Thresholds This switch family is TTL compatible (0.8V and 2.4V) over a supply range of 2V to 11V. At 12V the VIH level is about 2.5V. This is still below the TTL guaranteed high output minimum level of 2.8V, but noise margin is reduced. For best results with a 12V supply, use a logic family that provides a VOH greater than 3V. The digital input stages draw supply current whenever the digital input voltage is not at one of the supply rails. Driving the digital input signals from GND to V+ with a fast transition time minimizes power dissipation. High-Frequency Performance In 50Ω systems, signal response is reasonably flat even past 100MHz (see Figure 13). Figure 13 also illustrates that the frequency response is very consistent over varying analog signal levels. An OFF switch acts like a capacitor and passes higher frequencies with less attenuation, resulting in signal feedthrough from a switch’s input to its output. Off Isolation is the resistance to this feed-through, while Crosstalk indicates the amount of feed-through from one switch to another. Figure 14 details the high Off Isolation and Crosstalk rejection provided by this family. At 10MHz, Off Isolation is about 55dB in 50Ω systems, decreasing approximately 20dB per decade as frequency increases. Higher load impedances decrease Off Isolation and Crosstalk rejection due to the voltage divider action of the switch OFF impedance and the load impedance. FIGURE 8. OVERVOLTAGE PROTECTION 9 FN6042.3 February 24, 2012 ISL84524, ISL84525 Leakage Considerations Reverse ESD protection diodes are internally connected between each analog-signal pin and both V+ and GND. One of these diodes conducts if any analog signal exceeds V+ or GND. Virtually all the analog leakage current comes from the ESD diodes to V+ or GND. Although the ESD diodes on a given signal pin are identical and therefore fairly well balanced, they are reverse biased differently. Each is biased by either V+ or GND and the analog signal. This means their leakages will vary as the signal varies. The difference in the two diode leakages to the V+ and GND pins constitutes the analog-signal-path leakage current. All analog leakage current flows between each pin and one of the supply terminals, not to the other switch terminal. This is why both sides of a given switch can show leakage currents of the same or opposite polarity. There is no connection between the analog signal paths and V+ or GND.

These package dimensions are within allowable dimensions of JEDEC MO-187BA. 2. Dimensioning and tolerancing per ANSI Y14.5M-1994. 3. Dimension “D” does not include mold flash, protrusions or gate burrs and are measured at Datum Plane. Mold flash, protrusion and gate burrs shall not exceed 0.15mm (0.006 inch) per side. 4. Dimension “E1” does not include interlead flash or protrusions and are measured at Datum Plane. - H - Interlead flash and protrusions shall not exceed 0.15mm (0.006 inch) per side. 5. Formed leads shall be planar with respect to one another within 0.10mm (.004) at seating Plane. 6. “L” is the length of terminal for soldering to a substrate. 7. “N” is the number of terminal positions. 8. Terminal numbers are shown for reference only. 9. Dimension “b” does not include dambar protrusion. Allowable dambar protrusion shall be 0.08mm (0.003 inch) total in excess of “b” dimension at maximum material condition. Minimum space between protrusion and adjacent lead is 0.07mm (0.0027 inch). 10. Datums -A -H- . and - B - to be determined at Datum plane 11. Controlling dimension: MILLIMETER.
