MAX4638/MAX4639 3.5, Single 8:1 and Dual 4:1, Low-Voltage Analog Multiplexers General Description Features The MAX4638/MAX4639 are single 8:1 and dual 4:1 Guaranteed R ON CMOS analog multiplexers/demultiplexers (muxes/ 3.5 (+5V or 2.5V Supplies) demuxes). Each mux operates from a single +1.8V to 6 (+3V Supply) +5V supply or dual 2.5V supplies. These devices fea- Guaranteed 0.4 R Match Between Channels ON ture 3.5 on-resistance (R ) when powered with a ON single +5V supply and have -75dB off-isolation and Guaranteed 1 R Flatness Over Signal Range ON -85dB crosstalk from the output to each off channel. Guaranteed Low Leakage Currents The switching times are 18ns t and 7ns t . They ON OFF 0.25nA at +25C feature a -3dB 85MHz bandwidth and a guaranteed 0.25nA leakage current at +25C. Switching Times: t = 18ns, t = 7ns ON OFF A +1.8V to +5.5V operating range makes the MAX4638/ +1.8V to +5.5V Single-Supply Operation MAX4639 ideal for battery-powered, portable instru- 2.5V Dual-Supply Operation ments. All channels guarantee break-before-make Rail-to-Rail Signal Handling switching. These parts feature bidirectional operation and can handle Rail-to-Rail analog signals. All control TTL/CMOS-Logic Compatible inputs are TTL/CMOS-logic compatible. Decoding is in Crosstalk: -80dB (1MHz) standard BCD format, and an enable input is provided to Off-Isolation: -60dB (10MHz) simplify cascading of devices. These devices are avail- able in small 16-pin TQFN, TSSOP, and SO packages, as Ordering Information well as a 20-pin TQFN package.

A and EN are clamped only to V- and can exceed V+ up to their maximum ratings. Limit forward-diode current to maximum current rating. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
