They have three 8 supply pins: VCC, VEE, and GND. VCC and VEE are used to drive the internal CMOS switches and set the limits of the analog voltage on any switch. Reverse ESDprotection diodes are internally connected between each analog-signal pin and both VCC and VEE. If any analog signal exceeds VCC or VEE, one of these diodes _______________________________________________________________________________________ Low-Voltage, CMOS Analog Multiplexers/Switches MAX4581/MAX4582/MAX4583 Table 1.

During normal operation, these and other reverse-biased ESD diodes leak, forming the only current drawn from VCC or VEE. 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 VCC or VEE and the analog signal. This means their leakages will vary as the signal varies. The difference in the two diode leakages to the VCC and VEE 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 either the same or opposite polarity. There is no connection between the analog-signal paths and GND. VCC and GND power the internal logic and logic-level translators, and set the input logic limits. The logic-level translators convert the logic levels into switched V CC and VEE 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. VCC and VEE have ESD-protection diodes to GND. The logic-level thresholds are TTL/CMOS compatible when VCC is +5V. As VCC rises, the threshold increases _______________________________________________________________________________________ 9 MAX4581/MAX4582/MAX4583 Low-Voltage, CMOS Analog Multiplexers/Switches slightly, so when VCC reaches +12V the threshold is about 3.1V (above the TTL-guaranteed high-level minimum of 2.8V, but still compatible with CMOS outputs). VCC D1 EXTERNAL BLOCKING DIODE Bipolar Supplies These devices operate with bipolar supplies between ±2V and ±5V. The VCC and VEE supplies need not be symmetrical, but their sum cannot exceed the +13V absolute maximum rating Single Supply These devices operate from a single supply between +2V and +12V when VEE is connected to GND. All of the bipolar precautions must be observed. At room temperature, they actually “work” with a single supply near or below +1.7V, although as supply voltage decreases, switch on-resistance and switching times become very high. Overvoltage Protection Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maximum ratings because stresses beyond the listed ratings can cause permanent damage to the devices. Always sequence VCC on first, then VEE, followed by the logic inputs and analog signals. If power-supply sequencing is not possible, add two small signal diodes (D1, D2) in series with the supply pins for overvoltage protection (Figure 1). Adding diodes reduces the analog-signal range to one diode drop below VCC and one diode drop above VEE, but does not affect the devices’ low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between VCC and VEE should not exceed 13V. These protection diodes are not recommended when using a single supply if signal levels must extend to ground. 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 turning the switch on, but turning it off. The offstate switch acts like a capacitor and passes higher frequencies with less attenuation. At 10MHz, off isolation is about -50dB in 50Ω systems, becoming worse (approximately 20dB per decade) as frequency increases. Higher circuit impedances also degrade off isolation. Adjacent channel attenuation is about 3dB above that of a bare IC socket and is entirely due to capacitive coupling. 10 MAX4581 MAX4582 MAX4583 VCC * * X, Y, Z X_, Y_, Z_ * * VEE D2 EXTERNAL BLOCKING DIODE VEE *INTERNAL PROTECTION DIODES Figure 1. Overvoltage Protection Using External Blocking Diodes Pin Nomenclature The MAX4581/MAX4582/MAX4583 are pin-compatible with the industry-standard 74HC4051/74HC4052/ 74HC4053 and the MAX4051/MAX4052/MAX4053. They function identically and have identical logic diagrams, although these parts differ electrically. The pin designations and logic diagrams in this data sheet conform to the original 1972 specifications published by RCA for the CD4051/CD4052/CD4053. These designations differ from the standard Maxim switch and mux designations as found all other Maxim data sheets (including the MAX4051/MAX4052/MAX4053) and may cause confusion. Designers who feel more comfortable with Maxim’s standard designations are advised that the pin designations and logic diagrams on the MAX4051/MAX4052/MAX4053 data sheet may be freely applied to the MAX4581/MAX4582/MAX4583. ______________________________________________________________________________________ Low-Voltage, CMOS Analog Multiplexers/Switches VCC VA, VB, VC A 50Ω VA, VB, VC VCC X0 B VCC X1–X6 VX0 X7 ENABLE 90% VEE VOUT X GND 50% 0V C MAX4581 VCC VEE 0V VOUT 35pF 90% VX7 300Ω VEE tTRANS tTRANS VCC VA, VB VA, VB VCC A B X0, Y0 VCC VX0, VY0 MAX4582 X3, Y3 ENABLE 90% VEE X, Y GND 50% 0V X1, X2, Y1, Y2 50Ω VCC VOUT VEE 35pF 0V VOUT 90% VX3, VY3 300Ω VEE tTRANS tTRANS VCC VA, VB, VC VCC VA, VB, VC X1, Y1, Z1 A, B, C VEE 0V MAX4583 ENABLE GND VCC X, Y, Z VEE 35pF VEE 90% 0V VOUT 300Ω 50% VX0, VY0, VZ0 50Ω X2, Y2, Z2 VCC VOUT 90% VX1, VY1, VZ1 tTRANS tTRANS VEE = 0V FOR SINGLE-SUPPLY OPERATION.
