19-4725; Rev 4; 9/08 Improved, 8-Channel/Dual 4-Channel, CMOS Analog Multiplexers _______________General Description www.DataSheet4U.net ____________________________Features ♦ Pin-Compatible Plug-In Upgrades for Industry Standard DG408/DG409 ♦ Guaranteed Matching Between Channels, 8Ω Max ♦ Guaranteed On-Resistance Flatness, 9Ω Max ♦ Guaranteed Low Charge Injection, 15pC Max ♦ Low On-Resistance, 100Ω Max ♦ Input Leakage, 5nA Max at +85°C ♦ Low Power Consumption, 1.25mW Max ♦ Rail-to-Rail Signal Handling ♦ Digital Input Controls TTL/CMOS Compatible ♦ ESD Protection >2000V per Method 3015.7 DG408/DG409 Maxim’s redesigned DG408 and DG409 CMOS analog multiplexers now feature guaranteed matching between channels (8Ω max) and flatness over the specified signal range (9Ω max). These low on-resistance muxes (100Ω max) conduct equally well in either direction and feature guaranteed low charge injection (15pC max). In addition, these new muxes offer low input off-leakage current over temperature—less than 5nA at +85°C. The DG408 is a 1-of-8 multiplexer/demultiplexer and the DG409 is a dual 4-channel multiplexer/demultiplexer. Both muxes operate with a +5V to +30V single supply and with ±5V to ±20V dual supplies. ESD protection is guaranteed to be greater than 2000V per Method 3015.7 of MIL-STD-883. These improved muxes are pin-compatible plug-in upgrades for the industry standard DG408 and DG409.
