DG417/DG418/DG419 19-0114 Rev 2 12/96 Improved, SPST/SPDT Analog Switches General Description New Features Plug-In Upgrades for Industry-Standard Maxims redesigned DG417/DG418/DG419 precision, DG417/DG418/DG419 CMOS, monolithic analog switches now feature guar- anteed on-resistance matching (3 max) between Improved R Match Between Channels DS(ON) switches and guaranteed on-resistance flatness over (3 max, DG419 only) the signal range (4 max). These switches conduct Guaranteed R Over Signal Range (4 max) FLAT(ON) equally well in either direction and guarantee low Improved Charge Injection (10pC max) charge injection, low power consumption, and an ESD Improved Off-Leakage Current Over Temperature tolerance of 2000V minimum per Method 3015.7. The (<5nA at +85C) new design offers low off-leakage current over temper- ature (less than 5nA at +85C). Withstand Electrostatic Discharge (2000V min) per Method 3015.7 The DG417/DG418 are single-pole/single-throw (SPST) switches. The DG417 is normally closed, and the Existing Features DG418 is normally open. The DG419 is single- Low R (35 max) DS(ON) pole/double-throw (SPDT) with one normally closed switch and one normally open switch. Switching times Single-Supply Operation +10V to +30V are less than 175ns max for t and less than 145ns Bipolar-Supply Operation 4.5V to 20V ON max for t . Operation is from a single +10V to +30V OFF Low Power Consumption (35W max) supply, or bipolar 4.5V to 20V supplies. The Rail-to-Rail Signal Handling improved DG417/DG418/DG419 are fabricated with a TTL/CMOS-Logic Compatible 44V silicon-gate process. Ordering Information Applications PART TEMP.

Limit forward current to maximum current ratings. 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.
