The MAX4503 is normally open (NO). The MAX4504 is normally closed (NC). These CMOS switches can operate continuously with dual supplies between ±1.V and ±6V. 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 is CMOS-logic compatible when using ±5V supplies. A unique logic input architecture allows this even though the parts have no ground pin. For single-supply operation, use the MAX4501/ MAX4502, which are pin-for-pin equivalents.

Either may be considered as an input or output; signals pass equally well in both directions. __________Applications Information Power-Supply Considerations The MAX4503/MAX4504’s construction is typical of most CMOS analog switches, except they have only two supply pins: V+ and V-. These voltages set the analog voltage limits of the switch. Reverse ESD-protection diodes are internally connected between IN and each analog signal pin and both V+ and V-. If any analog signal exceeds V+ or V-, one of these diodes will conduct. During normal operation, these (and other) reverse-biased ESD diodes leak, forming the only current drawn from V-. Additional current flows through V+ from the logic-level translator. Virtually all the analog leakage current is provided through 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 V- 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 Vpins 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 either the same or opposite polarity. There is no connection between the analog signal paths and V+ or V-. V+ and V- also power the internal logic and logic-level translators. Since there is no ground pin, the logic input 6 has a low-current pull-up to V+ and the logic limit is set by an internal comparator referenced to V+. The logiclevel translators convert the logic levels to switched V+ and V- signals, to drive the gates of the analog signals. 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 V-. The logic is CMOS compatible when V+ is +5V. CMOS compatibility is maintained with all V+ values, assuming that the CMOS logic is operated from the same V+ supply. Since the MAX4503/MAX4504 have no ground pins, the logic levels are internally referenced to V+. Do not connect the MAX4503/MAX4504 V+ to +3V and 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 50MHz. (see Typical Operating Characteristics). Above 20MHz the on-response has several minor peaks which are highly layout dependent. The problem is not in turning the switch on, but in turning it off. The off-state switch acts like a capacitor, and passes higher frequencies with less attenuation. At 10MHz, off isolation is about -65dB in 50Ω systems, becoming worse (approximately 20dB per decade) as frequency increases. Higher circuit impedances also make off isolation worse. _______________________________________________________________________________________ Low-Voltage, Dual-Supply, SPST, CMOS Analog Switches V+ VIN NO 0V VNO MAX4503 VIN VOUT COM IN 50% VIN V+ 90% 90% VOUT VOUT V50Ω 35pF 1k 0V V- tON tOFF V+ VIN NC 0V VNC MAX4504 VIN VOUT COM IN 90% VOUT V50Ω 50% VIN V+ 1k 90% VOUT 35pF 0V V- tOFF tON Figure 1.
