19-1162; Rev 0; 12/96 Low-Voltage, CMOS Analog Multiplexers/Switches with Enable Inputs and Address Latching ____________________________Features The MAX4530/MAX4531/MAX4532 are low-voltage, CMOS analog ICs configured as an 8-channel multiplexer (mux) (MAX4530), two 4-channel muxes (MAX4531), and three single-pole/double-throw switches (MAX4532). These devices are pin compatible with the industry-standard 74HC4351/74HC4352/ 74HC4353. All devices have two complementary switch-enable inputs and address latching. The MAX4530/MAX4531/MAX4532 operate from a single supply of +2V to +12V, or from dual supplies of ±2V to ±6V. On-resistance (150Ω max) is matched between switches to 8Ω max. Each switch can handle rail-to-rail analog signals. Off-leakage current is only 1nA at TA = +25°C and 50nA at TA = +85°C. All digital inputs have 0.8V and 2.4V logic thresholds, ensuring both TTL- and CMOS-logic compatibility when using ±5V or a single +5V supply. ♦ Pin Compatible with 74HC4351/74HC4352/74HC4353 ♦ ±2.0V to ±6V Dual Supplies +2.0V to +12V Single Supply ♦ 75ΩSignal Paths with ±5V Supplies 150ΩSignal Paths with +5V Supply ♦ Rail-to-Rail Signal Handling ♦ tON and tOFF = 150ns and 120ns at ±4.5V ♦ <1µW Power Consumption ♦ >2kV ESD Protection per Method 3015.7 ♦ TTL/CMOS-Compatible Inputs ♦ Small, 20-Pin SSOP/SO/DIP Packages ______________Ordering Information ________________________Applications Battery-Operated Equipment PART TEMP.

Note 6: Leakage parameters are 100% tested at maximum rated hot operating temperature, and guaranteed by correlation at TA = +25°C. Note 7: Worst-case isolation is on channel 4 because of its proximity to the COM pin. Off isolation = 20log VCOM / VNO, VCOM = output, VNO = input to off switch.

They have three supply pins: V+, V-, and GND. V+ and V- drive 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 analog 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 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 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. For this reason, both sides of a given switch can show leakage currents of either the same or opposite polarity. The analog-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 MAX4530/MAX4531/MAX4532 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 MAX4530/MAX4531/MAX4532 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 50Ωsystems, 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 like a capacitor and passes higher frequencies with less attenuation. At 10MHz, off isolation is about -65dB in 50Ωsystems, becoming worse (approximately 20dB 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 MAX4530/MAX4531/MAX4532 __________Applications Information MAX4530/MAX4531/MAX4532 Low-Voltage, CMOS Analog Multiplexers/Switches with Enable Inputs and Address Latching ______________________________________________Test Circuits/Timing Diagrams V+ VADD_ 50Ω LE V+ V+ ADDC NO0 ADDB NO1–NO6 ADDA NO7 +3V 50% VADD_ 0V -3V COM VNO0 VOUT 90% MAX4530 V+ 300Ω EN2 EN1 35pF VOUT 0V 90% V- GND VNO7 V- tTRANS tTRANS V+ VADD_ LE V+ V+ NO0 ADDA 50Ω MAX4531 0V -3V COM EN1 GND VNO0 VOUT 300Ω EN2 50% VADD_ NO1_, NO2_ ADDB NO3_ V+ +3V 35pF 90% VOUT 0V 90% VVNO3 V- tTRANS tTRANS V+ VADD_ LE V+ V+ NO_ ADD_ +3V 50% VADD_ 0V 50Ω NC_ MAX4532 V+ COM GND VNC_ VOUT 300Ω EN2 EN1 -3V 35pF 90% VOUT 0V 90% VVNO_ V- tTRANS Figure 1.
