Description
The MAX317/MAX318/MAX319 are precision, CMOS, monolithic analog switches. The single-pole single-throw (SPST) MAX317 is normally closed (NC), the SPST MAX318 is normally open (NO), and the single-pole double-throw (SPDT) MAX319 has one normally open and one normally closed switch. All three parts offer low on resistance (less than 35Ω), guaranteed to match within 2Ω between channels and to remain flat over the analog signal range (Δ3Ω max). They also offer low leakage (less than 250pA at +25°C and less than 6nA at +85°C) and fast switching (turn-on time less than 175ns and turn-off time less than 145ns).

The MAX317/MAX318/MAX319 are fabricated with Maxim's new improved 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.

Key Features   Applications/Uses
  • Low On Resistance < 20Ω Typical (35Ω Max)
  • Guaranteed Matched On Resistance Between Channels < 2Ω
  • Guaranteed Flat On Resistance over Analog Signal Range Δ3Ω Max

  • Guaranteed Off-Channel Leakage < 6nA at +85°C
  • ESD Guaranteed > 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
