It offers RON matching between switches to 0.3Ω (max) and RON flatness of 1Ω (max) over the specified signal range. Each switch can handle V+ to GND analog signals. Off-leakage current is only 0.1nA (max) at +25°C. The MAX4634 features fast turn-on (tON) and turn-off (tOFF) times of 18ns and 11ns, respectively. All this comes in the tiny 10-pin µMAX and 10-pin, 3mm x 3mm, thin QFN packages.

CMOS switch construction allows processing of analog signals that are within the supply voltage range (GND to V+). To disable all switch channels, drive EN low. All four inputs and COM become high impedance during this state. If the disable feature is not needed, connect EN to V+. Applications Information Power-Supply Sequencing and Overvoltage Protection Proper power-supply sequencing is recommended for all CMOS devices. Always apply V+ before applying analog signals or logic inputs, especially if the analog or D2 GND * INTERNAL PROTECTION DIODES Figure 1. Overvoltage Protection Using External Blocking Diodes logic signals are not current limited. If this sequencing is not possible, and if the analog or logic inputs are not current limited to < 20mA, add a small-signal diode (D1) as shown in Figure 1. If the analog signal can dip below GND, add D2. Adding protection diodes reduces the analog signal range to a diode drop (about 0.7V) below V+ for D1 or to a diode drop above ground for D2. The addition of diodes does not affect leakage. Onresistance increases by a small amount at low supply voltages. Maximum supply voltage (V+) must not exceed 6V. Protection diodes D1 and D2 also protect against some overvoltage situations. A fault voltage up to the absolute maximum rating at an analog signal input does not damage the device, even if the supply voltage is below the signal voltage. _______________________________________________________________________________________ 7 Fast, Low-Voltage, 4Ω, 4-Channel CMOS Analog Multiplexer MAX4634 Test Circuits/Timing Diagrams VEN = VIH + 0.5 V+ VEN 0 V+ EN tR < 5ns tF < 5ns 50% NO1 V+ NO2–NO4 A0 VOUT MAX4634 90% 90% A1 COM VOUT GND 50Ω V+ 35pF 300Ω 0 tON tOFF Figure 2.
