DG308B - Improved Quad CMOS Analog Switches

General Description

The DG308B, DG309B analog switches are highly improved versions of the industry-standard DG308A, DG309.

These devices are fabricated in Vishay Siliconix’ proprietary silicon gate CMOS process, resulting in lower on-resistance, lower leakage, higher speed, and lower power consumption.

Key Features

  • ± 22 V supply voltage rating.
  • CMOS compatible logic.
  • Low on-resistance - RDS(on): 45 .
  • Low leakage - ID(on): 20 pA.
  • Single supply operation possible.
  • Extended temperature range.
  • Fast switching - tON: < 200 ns.
  • Low glitching - Q: 1 pC.

DG308B, DG309B Vishay Siliconix Improved Quad CMOS Analog Switches DESCRIPTION The DG308B, DG309B analog switches are highly improved versions of the industry-standard DG308A, DG309. These devices are fabricated in Vishay Siliconix’ proprietary silicon gate CMOS process, resulting in lower on-resistance, lower leakage, higher speed, and lower power consumption. These quad single-pole single-throw switches are designed for a wide variety of applications in telecommunications, instrumentation, process control, computer peripherals, etc. An improved charge injection compensation design minimizes switching transients. The DG308B and DG309B can handle up to ± 22 V input signals. An epitaxial layer prevents latchup.
