DG469, DG470 Vishay Siliconix High Voltage, Single and Dual Supply SPDT Analog Switch with Enable Pin DESCRIPTION FEATURES The DG469, DG470 are high voltage SPDT switches, with a Low on resistance (3.6 typical) typical on resistance of 3.6 and typical flatness of 0.4 . On resistance flatness (0.4 typical) The DG469, DG470 are identical, except the DG470 44 V supply maximum rating RoHS provides an enable input. When the enable input is activated, 15 V analog signal range COMPLIANT both sides of the switch are in a high impedance mode (Off), Fully specified at supply voltages of 4.5 V, 12 V and 15 V maintaining aSafe Stat at power up. This function can TTL/CMOS compatible also be used as a quickdisconnec in the event of a fault Break before make switching guaranteed condition. For audio switching, the enable pin provides a Total harmonic distortion 0.0145 % mute function. These are high voltage switches that are fully Compliant to RoHS Directive 2002/95/EC specified with dual supplies at 4.5 V and 15 V and a single supply of 12 V over an operating temperature range APPLICATIONS from - 40 C to + 125 C. Fast switching speeds coupled with high signal bandwidth makes these parts suitable for video Audio and video signal switching switching applications. All digital inputs have 0.8 V and 2.4 V Precision automatic test equipment logic thresholds ensuring low voltage TTL/CMOS Precision data acquisition compatibility. Each switch conducts equally well in both Relay replacement directions when on and can handle an input signal range that Communications systems extends to the supply voltage rails. They exhibit break- Automotive applications before-make switching action to prevent momentary shorting Sample and hold systems when switching between channels. The DG469, DG470 are Power routing applications offered in a MSOP 8 and SOIC 8 package.
