The MAX4501 is normally open (NO). The MAX4502 is normally closed (NC). These CMOS switches can operate continuously with a single supply between +2V and +12V. Each switch can handle Rail-to-Rail® analog signals. The off-leakage current is only 1nA at +25°C or 10nA at +85°C. The digital input has 0.8V and 2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +5V supply.

Any may be considered as an input or an output; signals pass equally well in both directions. Applications Information Power-Supply Considerations The MAX4501/MAX4502 are constructed like most CMOS analog switches, except they have only two supply pins: V+ and GND. V+ and GND drive the internal CMOS switches and set the analog voltage limits of the switch. 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. During normal operation, these and other reverse-biased ESD diodes leak, forming the only current drawn from V+ or GND. Virtually all the analog leakage current comes from the ESD diodes. 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. V+ and GND also power the internal logic and logiclevel translators, and set the input logic limits. The logic-level translators convert the logic levels to switched V+ and GND signals to drive the analog sig- 6 nal gates. This drive signal is the only connection between the logic supplies (and signals) and the analog supplies. COM, NO, and NC pins have ESD-protection diodes to V+ and GND. The logic-level thresholds are CMOS/TTL compatible when V+ is +5V. As V+ rises, the threshold increases slightly. When V+ reaches +12V, the logic-level threshold is about 3V—above the TTL guaranteed high-level minimum of 2.8V, but still compatible with CMOS outputs. Do not connect the MAX4501/MAX4502’s V+ pin to +3V and then connect the logic-level pins to TTL logic-level signals. TTL levels can exceed +3V and violate the absolute maximum ratings, damaging the part and/or external circuits. High-Frequency Performance In 50Ω systems, signal response is reasonably flat up to 250MHz (see Typical Operating Characteristics). Above 20MHz, the on-response has several minor peaks that are highly layout dependent. The problem is not in turning the switch on; it’s in turning it off. The offstate switch acts like a capacitor and passes higher frequencies with less attenuation. At 10MHz, off-isolation is about -60dB in 50Ω systems, decreasing approximately 20dB per decade as frequency increases. Higher circuit impedances also cause off-isolation to decrease. Adjacent channel attenuation is about 3dB above that of a bare IC socket, and is due entirely to capacitive coupling. _______________________________________________________________________________________ Low-Voltage, SPST, CMOS Analog Switches V+ +3V V+ NO 0 VNO MAX4501 VIN VOUT COM IN GND 50Ω 50% VIN 90% 90% VOUT 1k 35pF 0 tOFF tON V+ +3V V+ NC 0 VNC MAX4502 VIN VOUT COM IN GND 50Ω 50% VIN 90% VOUT 1k 90% 35pF 0 tON tOFF Figure 1.
