Overview

Description

The HI-303 switch is a monolithic device fabricated using CMOS technology and our dielectric isolation process. This switch features break-before-make switching, low and nearly constant ON resistance over the full analog signal range, and low power dissipation.

The HI-303 is TTL compatible and has a logic "0" condition with an input less than 0.8V and a logic "1" condition with an input greater than 4V.

Features

  • Analog Signal Range (±15V Supplies) ±15V
  • Low Leakage at 25 °C 40pA
  • Low Leakage at 125 °C 1nA
  • Low On-Resistance at 25 °C 35Ω
  • Break-Before-Make Delay 60ns
  • Charge Injection 30pC
  • TTL, CMOS Compatible
  • Symmetrical Switch Elements
  • Low Operating Power (Typ) 1.0mW
  • Pb-Free Available (RoHS Compliant)

Comparison

Applications

  • Sample and Hold (i.e., Low Leakage Switching)
  • Op Amp Gain Switching (i.e., Low On-Resistance)
  • Portable, Battery Operated Circuits
  • Low Level Switching Circuits
  • Dual or Single Supply Systems
