DG469/470

Vishay Siliconix

High Voltage, Single and Dual Supply SPDT Analog Switch

with Enable Pin

DESCRIPTION

The DG469/470 are high voltage SPDT switches, with atypical on resistance of 3.6 Ω and typical flatness of 0.4 Ω.The DG469 and DG470 are identical, except the DG470provides 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 canalso be used as a quick \"disconnect\" in the event of a faultcondition. For audio switching, the enable pin provides amute function. These are high voltage switches that are fullyspecified with dual supplies at ± 4.5 V and ± 15 V and asingle supply of 12 V over an operating temperature rangefrom - 40 °C to + 125 °C. Fast switching speeds coupled withhigh signal bandwidth makes these parts suitable for videoswitching applications. All digital inputs have 0.8 V and 2.4 Vlogic thresholds ensuring low voltage TTL/CMOScompatibility. Each switch conducts equally well in bothdirections when on and can handle an input signal range thatextends to the supply voltage rails. They exhibit break-before-make switching action to prevent momentary shortingwhen switching between channels. The DG469 and DG470are offered in a MSOP 8 and SOIC 8 package.
