DG409CY+T

19-4725; Rev 4; 9/08 Improved, 8-Channel/Dual 4-Channel, CMOS Analog Multiplexers 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. ____________________________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 Ordering Information Applications Sample-and-Hold Circuits PART TEMP RANGE PIN-PACKAGE Test Equipment DG408CUE Guidance and Control Systems DG408CJ 0°C to +70°C 16 Plastic DIP Communications Systems DG408CY 0°C to +70°C 16 Narrow SO Data-Acquisition Systems DG408C/D 0°C to +70°C Dice* Audio Signal Routing DG408EUE 0°C to +70°C 16 TSSOP 0°C to +70°C 16 TSSOP DG408DJ -40°C to +85°C 16 Plastic DIP DG408DY -40°C to +85°C 16 Narrow SO Ordering Information continued at end of data sheet. *Contact factory for dice specifications. **Contact factory for availability and processing to MIL-STD-883.

Note 3: Guaranteed by design. Note 4: ΔRON = RON(MAX) - RON(MIN). On-resistance match between channels and flatness are guaranteed only with specified voltages. Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured at the extremes of the specified analog signal range. Note 5: Leakage parameters are 100% tested at the maximum rated hot temperature and guaranteed by correlation at +25°C. Note 6: Off isolation = 20log VD/VS, where VD = output and VS = input to off switch. 4 _______________________________________________________________________________________ Improved, 8-Channel/Dual 4-Channel, CMOS Analog Multiplexers ON-RESISTANCE vs. VD AND TEMPERATURE (DUAL SUPPLIES) ±5V +85°C 60 +25°C -55°C 40 ±20V 280 rDS(ON) (Ω) ±15V 40 5V 240 200 160 10V 120 20 20 0 -10 -5 0 5 10 15 20 -15 -10 -5 VD (V) 5 10 0 15 5 10 20 ON LEAKAGE vs. TEMPERATURE 1000 DG408/9 TOC-05 DG408/9 TOC-04 1000 V+ = 15V V- = -15V 100 15 VD (V) OFF LEAKAGE vs. TEMPERATURE V+ = 15V V- = 0V 140 0 VD (V) ON-RESISTANCE vs. VD AND TEMPERATURE (SINGLE SUPPLY) 160 20V 40 100 DG408/9 TOC-05 -15 15V 80 0 -20 V+ = 15V V- = -15V +125°C +25°C 80 -55°C 60 10 OFF LEAKAGE (nA) +85°C 100 ON LEAKAGE (nA) 120 1 ICOM (ON) 0.1 0.01 40 0 5 10 15 1 0.1 ICOM (ON) 0.001 0.0001 0.0001 -55 -35 -15 5 25 45 85 105 125 65 -55 -35 -15 TEMPERATURE (°C) VD (V) CHARGE INJECTION vs. VD 100 85 105 125 I+ 10 I+, I- (μA) V+ = 15V V- = -15V 0 V+ = 12V V- = 0V -10 65 DG408/9 TOC-08 20 10 25 45 5 TEMPERATURE (°C) SUPPLY CURRENT vs. TEMPERATURE 30 DG408/9 TOC-07 0 10 0.01 INO (OFF) 0.001 20 Qj (pC) rDS(ON) (Ω) 360 +125°C 80 80 60 400 320 rDS(ON) (Ω) rDS(ON) (Ω) 100 ±10V 100 V+ = 15V V- = -15V DG408/9 TOC-03 140 120 120 DG408/9 TOC-01 160 ON-RESISTANCE vs. VD (SINGLE SUPPLY) DG408/9 TOC-02 ON-RESISTANCE vs. VD (DUAL SUPPLIES) 1 0.1 I0.01 -20 -30 V+ = 15V V- = -15V VEN = VA = 0V, 4.5V 0.001 -15 -10 -5 0 VD (V) 5 10 15 -55 -35 -15 5 25 45 65 85 105 125 TEMPERATURE (°C) _______________________________________________________________________________________ 5 DG408/DG409 __________________________________________Typical Operating Characteristics (TA = +25°C, unless otherwise noted.) DG408/DG409 Improved, 8-Channel/Dual 4-Channel, CMOS Analog Multiplexers ______________________________________________________________Pin Description PIN NAME FUNCTION DG408 DG409 1, 15, 16 — A0, A2, A1 Address Inputs — 1, 16 A0, A1 Address Inputs 2 2 EN Enable Input 3 3 V- Negative Supply Voltage Input 4–7 — S1–S4 Bidirectional Analog Inputs — 4–7 S1A–S4A Bidirectional Analog Inputs 8 — D Bidirectional Analog Output — 8, 9 DA, DB Bidirectional Analog Outputs 9–12 — S8–S5 Bidirectional Analog Inputs — 10–13 S4B–S1B Bidirectional Analog Inputs 13 14 V+ 14 15 GND Positive Supply Voltage Input Ground Applications Information Operation with Supply Voltages Other than 15V Using supply voltages less than ±15V reduces the analog signal range. The DG408/DG409 switches operate with ±5V to ±20V bipolar supplies or with a +5V to +40V single supply. Connect V- to GND when operating with a single supply. Both device types can also operate with unbalanced supplies, such as +24V and -5V. The Typical Operating Characteristics graphs show typical on-resistance with 20V, 15V, 10V, and 5V supplies. (Switching times increase by a factor of two or more for operation at 5V.) Overvoltage Protection Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maximum ratings, because stresses beyond the listed ratings may cause permanent damage to the devices. Always sequence V+ on first, then V-, followed by the logic inputs, S or D. If power-supply sequencing is not possible, add two small signal diodes in series with supply pins for overvoltage protection (Figure 1). Adding diodes reduces the analog signal range to 1V below V+ and 1V above V-, but does not affect the devices’ low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between V+ and V- should not exceed +44V. 6 V+ DG408 DG409 S D Vg V- Figure 1.
