ISL54501, ISL54502 Features The Intersil ISL54501 and ISL54502 devices are low ON-resistance, low voltage, bi-directional, single pole/single throw (SPST) analog switches designed to operate from a single +1.8V to +5.5V supply. Targeted applications include battery powered equipment that benefit from low rON resistance (5Ω), excellent rON flatness, and fast switching speeds (tON = 22ns, tOFF = 15ns). The digital logic input is 1.8V CMOS compatible when using a single +3V supply. • ON-resistance (rON) - VCC = +5.0V . . . . . . . . . . . . . . . . . . . . . 5.0Ω - VCC = +3.0V . . . . . . . . . . . . . . . . . . . . . 7.0Ω - VCC = +1.8V . . . . . . . . . . . . . . . . . . . . . 13Ω Cell phones, for example, often face ASIC functionality limitations.

CAPACITANCE TEST CIRCUIT Detailed Description The ISL54501 and ISL54502 are bi-directional, single pole/single throw (SPST) analog switches. They offer precise switching capability from a single 1.8V to 5.5V supply with low ON-resistance and high speed operation. With a single supply of 5V the typical ON-resistance is only 5Ω, with a typical turn-on and turn-off time of: tON = 22ns, tOFF = 15ns. The devices are especially well suited for portable battery powered equipment due to their low operating supply voltage (1.8V), low power consumption (0.11µW), low leakage currents (300nA max), and tiny µTDFN package. The ISL54501 is a single normally open (NO) SPST analog switch. The ISL54502 is a single normally closed (NC) SPST analog switch. External V+ Series Resistor For improved ESD and latch-up immunity, Intersil recommends adding a 100Ω resistor in series with the V+ power supply pin of the ISL54501, ISL54502 IC (see Figure 6). During an overvoltage transient event (such as occurs during system level IEC 61000 ESD testing), substrate currents can be generated in the IC that can trigger parasitic SCR structures to turn ON, creating a low impedance path from the V+ power supply to ground. This will result in a significant amount of current flow in the IC, which can potentially create a latch-up state or permanently damage the IC. The external V+ resistor limits the current during this over-stress situation and has been found to prevent latch-up or destructive damage for many over voltage transient events. Under normal operation the sub-microamp IDD current of the IC produces an insignificant voltage drop across the 100Ω series resistor resulting in no impact to switch operation or performance. 8 V+ OPTIONAL PROTECTION RESISTOR C 100Ω NO COM NC IN GND FIGURE 6. V+ SERIES RESISTOR FOR ENHANCED ESD AND LATCH-UP IMMUNITY 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 7). 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 provided 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 easily be protected by adding a 1kΩ resistor in series with the input (see Figure 7). The resistor limits the input current below the threshold FN6550.2 October 26, 2009 ISL54501, ISL54502 that produces permanent damage, and the sub-microamp input current produces an insignificant voltage drop during normal operation. This family of switches cannot be operated with bipolar supplies, because the input switching point becomes negative in this configuration. 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 9) 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. Logic-Level Thresholds OPTIONAL SCHOTTKY DIODE V+ OPTIONAL PROTECTION RESISTOR VCOM GND OPTIONAL SCHOTTKY DIODE FIGURE 7. OVERVOLTAGE PROTECTION Power-Supply Considerations The ISL54501, ISL54502 construction is typical of most single supply CMOS analog switches in that they have two supply pins: V+ and GND. V+ and GND drive the internal CMOS switches and set their analog voltage limits. Unlike switches with a 4V maximum supply voltage, the ISL54501, ISL54502 5.5V maximum supply voltage provides plenty of room for the 10% tolerance of 3.6V supplies, as well as room for overshoot and noise spikes. The minimum recommended supply voltage is 1.8V but the part will operate with a supply below 1.8V. It is important to note that the input signal range, switching times, and ON-resistance degrade at lower supply voltages. Refer to the “Electrical Specifications” tables starting on page 4 the and “Typical Performance Curves” starting on page 10 for details. V+ and GND also power the internal logic and level shiftier. The level shiftier converts the input logic levels to switched V+ and GND signals to drive the analog switch gate terminals. 9 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 INX VNX This switch family is 1.8V CMOS compatible (0.5V and 1.4V) over a supply range of 2V to 3.6V (see Figure 14). At 3.6V the VIH level is about 0.98V. This is still below the 1.8V CMOS guaranteed high output minimum level of 1.4V, but noise margin is reduced. In 50Ω systems, the ISL54501, ISL54502 has a -3dB bandwidth of 350MHz (see Figure 15). The frequency response is very consistent over a wide V+ range, and for varying analog signal levels. An OFF switch behaves like a capacitor and passes higher frequencies with less attenuation, resulting in signal feedthrough from a switch’s input to output. Off isolation is the resistance of this signal feedthrough. Figure 16 details the high off isolation provided by the ISL54501, ISL54502. At 1MHz, off isolation is about 75dB in 50Ω systems, decreasing approximately 20dB per decade as frequency increases. Higher load impedances decrease off isolation due to the voltage divider action of the switch OFF impedance and the load impedance. 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.
