19-2522; Rev 3; 2/05 High-Speed, Low-Voltage, 0.7 CMOS Analog Switches/Multiplexers Features The MAX4781/MAX4782/MAX4783 are high-speed, low-voltage, low on-resistance, CMOS analog multiplexers/switches configured as an 8-channel multiplexer (MAX4781), two 4-channel multiplexers (MAX4782), and three single-pole/double-throw (SPDT) switches (MAX4783). These devices operate with a +1.6V to +3.6V single supply. When powered from a +3V supply, MAX4781/ MAX4782/MAX4783 feature a 0.7 on-resistance (RON), with 0.3 RON matching between channels, and 0.1 RON flatness. These devices handle rail-to-rail analog signals while consuming less than 3W of quiescent power. They are available in space-saving 16pin thin QFN (3mm x 3mm) and TSSOP packages.

There are two supply inputs: VCC and GND. VCC and GND drive the internal CMOS switches and set the limits of the analog voltage on any switch. Internal reverse ESD-protection diodes are connected between each analog signal input and both VCC and GND. If any analog signal exceeds VCC or GND, one of these diodes conducts. During normal operation, these and other reverse-biased ESD diodes leak, forming the only current drawn from VCC or GND. Virtually all the analog leakage current comes from the ESD diodes. Although the ESD diodes on a given signal input are identical and therefore fairly well balanced, they are reverse-biased differently. Each diode is biased by either VCC or GND and the analog signal. Their leakages vary as the signal varies. The difference in the two diodes' leakages to VCC and GND constitutes the analog-signal-path leakage current. All analog leakage current flows between each input and one of the supply terminals, not to the other switch terminal. Both sides of a given switch can show leakage currents of either the same or opposite polarity. VCC and GND power the internal logic and set the input logic limits. Logic inputs have ESD-protection diodes to ground. High-Frequency Performance In 50 systems, signal response is reasonably flat up to 50MHz (see the Typical Operating Characteristics). Above 20MHz, the on-response has several minor peaks that are highly layout dependent. In the off state, the switch acts like a capacitor and passes higher frequencies with less attenuation. At 10MHz, off-isolation is approximately -50dB in 50 systems, becoming worse (approximately 20dB per decade) as frequency increases. Higher circuit impedance also degrades offisolation. Adjacent channel attenuation is approximately 3dB above that of a bare IC socket and is entirely because of capacitive coupling. Pin Nomenclature The MAX4781/MAX4782/MAX4783 are pin compatible with the industry-standard 74HC4051/74HC4052/ 74HC4053 and the MAX4617/MAX4618/MAX4619. In single-supply applications, 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 found on other Maxim data sheets such as the MAX4051/ MAX4052/MAX4053. Designers who are more comfortable with Maxim's standard designations are advised that the pin designations and logic diagrams on the MAX4051/MAX4052/MAX4053 data sheet can be applied to the MAX4781/MAX4782/MAX4783. Power Supply The MAX4781/MAX4782/MAX4783 operate from a single supply between +1.6V and +3.6V. Switch on-resistance increases as the supply voltage is lowered. 8 _______________________________________________________________________________________ High-Speed, Low-Voltage, 0.7 CMOS Analog Switches/Multiplexers MAX4781/MAX4782/MAX4783 Table 1.
