DESCRIPTION
The DG469, DG470 are high voltage SPDT switches, with a
typical on resistance of 3.6
Ω and typical flatness of 0.4 Ω.
The DG469, DG470 are identical, except 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 break-
before-make switching action to prevent momentary shorting
when switching between channels. The DG469, DG470 are
offered in a MSOP 8 and SOIC 8 package.
