They have three supply pins: V+, V, and GND. V+ and V- drive the the internal CMOS switches and set the limits of the analog voltage on any switch. Reverse ESD-protection diodes are internally connected between each analog-signal pin and both V+ and V-. One of these diodes conducts if any signal exceeds V+ or V-. During normal operation, these and other reverse-biased ESD diodes leak, forming the only current drawn from V+ or V–. Virtually all of the analog leakage current comes from the ESD diodes. Although the ESD diodes on a given signal pine 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 vary as the signal varies. The difference in the two diode leakages to the V+ and V– 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. For this reason, both sides of a given switch can show leakage currents of either the same or opposite polarity. The signal paths and GND are not connected. V+ and GND power the internal logic and logic-level translators, and set both the input and output logic limits. The logic level translators convert the logic levels into switched V+ and V- signals to drive the analog signals’ gates. This drive signal is the only connection between the logic supplies and signals and the analog supplies. V+ and V- have ESD-protection diodes to GND. The logic-level thresholds are TTL/CMOS compatible when V+ = +5V. As V+ rises, the threshold increases slightly, so when V+ reaches +12V, the threshold is about 3.1V – above the TTL guaranteed, high-level minimum of 2.8V, but still compatible with CMOS outputs. Bipolar Supplies The PS4530/PS4531/PS4532 operate with bipolar supplies between ±2.0V and ±6V. The V+ and V- supplies need not be symmetrical, but their sum cannot exceed the +13V absolute maximum rating. Single Supply The PS4530/PS4531/PS4532 operate from a single supply between +2V and 12V when V- is connected to GND. All of the bipolar precautions must be observed. At room temperature, they actually work with a single supply at, near, or below +1.7V, although as supply voltage decreases, switch on-resistance and switching times become very high. High-Frequency Performance In 50Ohm systerns, signal response is reasonably flat up to 50MHz (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, but in turning it off. The off-state switch acts lilke a capacitor and passes higher frequencies with less attenuation. At 10MHz, off isolation is about –65dB in 50Ohm systems, becoming worse (approximately 21dB per decade) as frequency increases. Higher circuit impedances also make off isolation worse. Adjacent channel attenuation is about 3dB above that of a bare IC socket, and is due entirely to capacitive coupling. 9 PS8591D 11/17/04 21098765432121098765432109876543210987654321210987654321098765432109876543212109876543210987654321098765432121098765432109876543210987654321 21098765432121098765432109876543210987654321210987654321098765432109876543212109876543210987654321098765432121098765432109876543210987654321 PS4530/PS4531/PS4532 Precision 8-Ch, 2-Ch, Latched Analog Multiplexers/Switches Test Circuits/Timing Diagrams V+ V+ ADDC LE V+ ADDB 50Ohm ADDA NO1-NO6 VADD_ NO0 +3V 50% 0V VNO0 90% PI5A4530 V+ EN2 EN1 GND V- NO7 COM 300Ohm –3V 0V VOUT 35pF VOUT VNO7 ttrans 90% ttrans V– V+ VADD_ V+ ADDA LE V+ ADDB 50Ohm NO1_-NO2_ NO0 +3V VADD_ 50% 0V VNO0 PI5A4531 NO3_ V+ EN2 EN1 GND COM V300Ohm V– –3V VOUT 35pF 0V 90% VOUT VNO3 ttrans 90% ttrans V+ VADD_ V+ NO_ +3V ADD_ LE V+ VADD_ 50% 0V VNC_ 90% 50Ohm NC_ –3V PI5A4532 V+ EN2 EN1 GND COM V300Ohm V– VOUT 35pF 0V VOUT VNO_ ttrans 90% ttrans Figure 1.
