with a single supply near or below +2.5v, although as supply voltage decreases, switch on-resistance and switching times become very high. over-voltage protection proper power-supply sequencing is recommended for the cmos device. do not exceed the absolute maximum ratings because stresses beyond the listed ratings can cause permanent damage to the devices. always sequence v cc on first, then v ee , followed by the logic inputs and analog signals. if power-supply sequencing is not possible, add two small signal diodes (d1, d2) in series with the supply pins for over-voltage protection (figure 1). adding diodes reduces the analog-signal range to one diode drop below v cc and one diode drop above v ee, but does not affect the device?s low switch resistance and low leakage characteristics. device operation is unchanged, and the difference between v cc and v ee should not exceed 13.2v. these protection diodes are not recommended when using a single supply if signal levels must extend to ground. x_ * x v cc SGM4581 d1 external blocking diode d2 external blocking diode * ** * internal protection diodes figure 1. over-voltage protection using external blocking diodes SGM4581 high voltage, cmos analog multiplexer 12 sg micro corp www.sg-micro.com package outline dimensions soic-16 d e e1 e b a a1 a2 l c recommended land pattern (unit: mm) 5.60 1.75 1.27 0.65 dimensions in millimeters dimensions in inches symbol min max min max a 1.350 1.750 0.053 0.069 a1 0.100 0.250 0.004 0.010 a2 1.350 1.550 0.053 0.061 b 0.330 0.510 0.013 0.020 c 0.170 0.250 0.006 0.010 d 9.800 10.200 0.386 0.402 e 3.800 4.000 0.150 0.157 e1 5.800 6.200 0.228 0.244 e 1.27 bsc 0.050 bsc l 0.400 1.270 0.016 0.050 0 8 0 8 SGM4581 high voltage, cmos analog multiplexer 13 sg micro corp www.sg-micro.com package outline dimensions ssop-16 e e1 d a a1 a2 e b c l 0.635 0.406 5.588 1.651 recommended land pattern (unit: mm) dimensions in millimeters dimensions in inches symbol min max min max a 1.350 1.750 0.053 0.069 a1 0.100 0.250 0.004 0.010 a2 1.350 1.550 0.053 0.061 b 0.200 0.300 0.008 0.012 c 0.170 0.250 0.007 0.010 d 4.700 5.100 0.185 0.200 e 3.800 4.000 0.150 0.157 e1 5.800 6.200 0.228 0.244 e 0.635 bsc 0.025 bsc l 0.400 1.270 0.016 0.050 0 8 0 8 SGM4581 high voltage, cmos analog multiplexer 14 sg micro corp www.sg-micro.com package outline dimensions tssop-16 e1 e b e a a2 a1 c l h d 1.78 0.42 0.65 5.94 recommended land pattern (unit: mm) dimensions in millimeters dimensions in inches symbol min max min max a 1.100 0.043 a1 0.050 0.150 0.002 0.006 a2 0.800 1.000 0.031 0.039 b 0.190 0.300 0.007 0.012 c 0.090 0.200 0.004 0.008 d 4.900 5.100 0.193 0.201 e 4.300 4.500 0.169 0.177 e1 6.250 6.550 0.246 0.258 e 0.650 bsc 0.026 bsc l 0.500 0.700 0.02 0.028 h 0.25 typ 0.01 typ 1 7 1 7 SGM4581 high voltage, cmos analog multiplexer 15 sg micro corp www.sg-micro.com package outline dimensions tqfn-33-16l top view bottom view side view a a2 a1 e e1 b l k d1 d e n1 n5 n16 1.7 1.7 0.7 2.2 3.6 0.5 0.24 recommended land pattern (unit: mm) dimensions in millimeters dimensions in inches symbol min max min max a 0.700 0.800 0.028 0.031 a1 0.000 0.050 0.000 0.002 a2 0.203 ref 0.008 ref d 2.900 3.100 0.114 0.122 d1 1.600 1.800 0.063 0.071 e 2.900 3.100 0.114 0.122 e1 1.600 1.800 0.063 0.071 k 0.200 min 0.008 min b 0.180 0.300 0.007 0.012 e 0.500 typ 0.020 typ l 0.300 0.500 0.012 0.020 SGM4581 high voltage, cmos analog multiplexer 16 sg micro corp www.sg-micro.com tape and reel information note: the picture is only for reference. please make the object as the standard. key parameter list of tape and reel package type reel diameter reel width w1 (mm) a0 (mm) b0 (mm) k0 (mm) p0 (mm) p1 (mm) p2 (mm) w (mm) pin1 quadrant soic-16 13 16.4 6.5 10.3 2.1 4.0 8.0 2.0 16.0 q1 ssop-16 13 12.4 6.4 5.4 2.1 4.0 8.0 2.0 12.0 q1 tssop-16 13 12.4 6.9 5.6 1.2 4.0 8.0 2.0 12.0 q1 tqfn-33-16l 13 12.40 3.35 3.35 1.13 4.00 4.00 2.00 12.00 q1 reel width (w1) reel diameter reel dimensions tape dimensions direction of feed p2 p0 w p1 a0 k0 b0 q1 q2 q4 q3 q3 q4 q2 q1 q3 q4 q2 q1 SGM4581 high voltage, cmos analog multiplexer 17 sg micro corp www.sg-micro.com carton box dimensions note: the picture is only for reference. please make the object as the standard. key parameter list of carton box reel type length (mm) width (mm) height (mm) pizza/carton 13 386 280 370 5 |
