leakage characteristics. Device operation is un-
changed, and the difference between V+ and V- should
not exceed 44V. These protection diodes are not rec-
ommended when using a single supply.
Off-Isolation at High Frequencies
In 50
systems, the high-frequency on-response of
these parts extends from DC to above 300MHz, with a
typical loss of -3.6dB. When the switch is turned off,
however, it behaves like a capacitor, and off-isolation
decreases with increasing frequency. This effect is
more pronounced with higher source and load imped-
ances. Above 5MHz, circuit board layout becomes criti-
cal. The graphs shown in the Typical Operating
Characteristics were taken using a 50
source and
load connected with BNC connectors.
