Description
The GaAs FET IC SPDT non-reflective switch with integral
driver is offered in the SOIC-8 package. These devices are
useful as modulators as well as switches in
instrumentation and telecommunications applications. The
integral driver simplifies the external drive circuit, thus
saving PC board space and reducing component count.

6. Supply voltage must be connected before control voltage is applied. Use of
toggle switches or other similar components may produce voltage spikes
which can cause irreversible damage to the device.
7. Current increases from 4 mA to 5 mA at +85C.
