MAX361CPE+

19-0180; Rev 2; 6/04 Precision, Quad, SPST Analog Switches The MAX361/MAX362 are precision, quad, single-pole single-throw (SPST) analog switches. The MAX361 has four normally closed (NC) switches, and the MAX362 has four normally open (NO) switches. Both parts offer low channel on-resistance (less than 85Ω), guaranteed to match within 3Ω between channels and to remain flat over the analog signal range (∆9Ω max). Both parts also offer low leakage (less than 500pA at +25°C and less than 4nA at +85°C) and fast switching (turn-on time less than 250ns and turn-off time less than 170ns). The MAX361/MAX362 are fabricated with Maxim’s new improved 44V silicon-gate process. Design improvements guarantee extremely low charge injection (10pC), low power consumption (35µW), and electrostatic discharge (ESD) greater than 2000V. The 44V maximum breakdown voltage allows rail-to-rail analog signal handling capability. These monolithic switches operate with a single positive supply (+10V to +30V) or with split supplies (±4.5V to ±20V) while retaining CMOS-logic input compatibility and fast switching. CMOS inputs provide reduced input loading. ________________________Applications Sample-and-Hold Circuits Guidance and Control Systems Heads-Up Displays Test Equipment Communications Systems Battery-Operated Systems PBX, PABX ____________________________Features ♦ Low On Resistance: < 45Ω Typical (85Ω Max) ♦ Guaranteed Matched On-Resistance Between Channels: < 2Ω ♦ Guaranteed Flat On-Resistance over Analog Signal Range: ∆9Ω Max ♦ Guaranteed Charge Injection: < 10pC ♦ Guaranteed Off-Channel Leakage: 2000V per Method 3015.7 ♦ Single-Supply Operation (+10V to +30V) Bipolar-Supply Operation (±4.5V to ±20V) ♦ TTL-/CMOS-Logic Compatible ♦ Rail-to-Rail Analog Signal Handling Capability ______________Ordering Information PART TEMP RANGE PIN-PACKAGE MAX361CPE 0°C to +70°C 16 Plastic DIP MAX361CSE MAX361C/D MAX361ETE MAX361EPE 0°C to +70°C 0°C to +70°C -40°C to +85°C -40°C to +85°C 16 Narrow SO Dice* 16 Thin QFN 16 Plastic DIP MAX361ESE -40°C to +85°C MAX361EJE -40°C to +85°C MAX361MJE -55°C to +125°C MAX362CPE 0°C to +70°C MAX362CSE 0°C to +70°C MAX362C/D 0°C to +70°C MAX362ETE -40°C to +85°C MAX362EPE -40°C to +85°C MAX362ESE -40°C to +85°C MAX362EJE -40°C to +85°C MAX362MJE -55°C to +125°C *Contact factory for dice specifications. 16 Narrow SO 16 CERDIP 16 CERDIP 16 Plastic DIP 16 Narrow SO Dice* 16 Thin QFN 16 Plastic DIP 16 Narrow SO 16 CERDIP 16 CERDIP Pin Configurations/Functional Diagrams/Truth Tables TOP VIEW IN1 1 16 IN2 COM1 2 15 COM2 NC1 3 14 NC2 V- 4 13 V+ MAX361 GND 5 NC4 6 11 NC3 NO4 6 9 IN3 15 COM2 14 NO2 V- 4 GND 5 IN4 8 16 IN2 NO1 3 12 N.C. 10 COM3 COM4 7 IN1 1 COM1 2 13 V+ MAX362 11 NO3 10 COM3 COM4 7 9 IN4 8 DIP/SO IN3 DIP/SO MAX361 LOGIC SWITCH 0 1 12 N.C.

The MAX361/MAX362 switches operate with bipolar supplies of ±4.5V to ±20V. Typical operating characteristic graphs show typical on resistance for ±15V, ±10V, and ±5V supplies. Switching times increase by a factor of two or more for ±5V operation. The MAX361/MAX362 can also operate from +10V to +30V unipolar supplies. Both parts can also be powered from unbalanced supplies such as +24V and -5V. Connect V- to 0V when operating with a single supply. 6 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, followed by V-, and logic inputs. If power-supply sequencing is not possible, add two small signal diodes in series with the supply pins for overvoltage protection (Figure 6). Adding the diodes reduces the analog signal range to 1V below V+ and 1V below V-, but low switch resistance and low leakage characteristics are unaffected. Device operation is unchanged, and the difference from V+ to Vshould not exceed +44V. _______________________________________________________________________________________ Precision, Quad, SPST Analog Switches MAX361/MAX362 +15V LOGIC INPUT +3V SWITCH INPUT tf < 20ns tr < 20ns 50% SWITCH OUTPUT V+ NO_ OR NC_ VO 1N_ 0V SWITCH V INPUT COM COM_ VCOM 35pF RL tOFF VO 0.8VO 0.8VO GND LOGIC INPUT +3V V- -15V 0V REPEAT TEST FOR CHANNELS 2, 3, AND 4. tON FOR LOAD CONDITIONS, SEE SPECIFICATIONS CL (INCLUDES FIXTURE AND STRAY CAPACITANCE) RL VO = VCOM RL + RON LOGIC INPUT WAVEFORM IS INVERTED FOR SWITCHES THAT HAVE THE OPPOSITE LOGIC SENSE.
