The PE42540 has a maximum 25 kHz switching
rate when the internal negative voltage generator
is used (pin 31 = GND). The rate at which the
PE42540 can be switched is only limited to the
switching time (Table
1)
if an external negative
supply is provided at (pin 31 = Vss
EXT
).

For proper operation, the Vss
EXT
control pin must
be grounded or tied to the Vss voltage specified
in
Table 3.
When the Vss
EXT
control pin is
grounded, FETs in the switch are biased with an
internal voltage generator. For applications that
require the lowest possible spur performance,
Vss
EXT
can be applied externally to bypass the
internal negative voltage generator.
Spurious Performance
The typical spurious performance of the PE42540
is -144 dBm when Vss
EXT
= 0V (pin 31 = GND). If
further improvement is desired, the internal
negative voltage generator can be disabled by
setting Vss
EXT
= -V

Exceeding absolute maximum ratings may cause
permanent damage. Operation should be
restricted to the limits in the Operating Ranges
table. Operation between operating range
maximum and absolute maximum for extended
periods may reduce reliability.
Electrostatic Discharge (ESD) Precautions
When handling this UltraCMOS
®
device, observe
the same precautions that you would use with
other ESD-sensitive devices. Although this device
contains circuitry to protect it from damage due to
ESD, precautions should be taken to avoid
exceeding the specified rating.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS
®
devices are immune to latch-up.
Moisture Sensitivity Level
The Moisture Sensitivity Level rating for the
PE42540 in the 32-lead 5x5 mm LGA package is
MSL3.
