The DG470 is high voltage SPDT switches, with a typical on resistance of 3.6 O and typical flatness of 0.4 O. The DG470 provides an enable input. When the enable input is activated, both sides of the switch are in a high impedance mode (Off), maintaining a “Safe State” at power up. This function can also be used as a quick “disconnect” in the event of a fault condition. For audio switching, the enable pin provides a mute function. These are high voltage switches that are fully specified with dual supplies at ± 4.5 V and ± 15 V and a single supply of 12 V over an operating temperature range from – 40 °C to + 125 °C. Fast switching speeds coupled with high signal bandwidth makes these parts suitable for video switching applications. All digital inputs have 0.8 V and 2.4 V logic thresholds ensuring low voltage TTL/CMOS compatibility. Each switch conducts equally well in both directions when on and can handle an input signal range that extends to the supply voltage rails. They exhibit breakbefore-make switching action to prevent momentary shorting when switching between channels. The DG470 is offered in a MSOP 8 and SOIC 8 package.
