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 rating specified in Table 4.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS
devices are immune to latch-up.
Table 3. Operating Ranges
Notes: 1.
All RF pins must be DC blocked with an external series
capacitor or held at 0 VDC.
Figure 3. Pin Configuration
Table 5. Control Logic Truth Table
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.

Control Logic Input
The control logic input pin (CTRL) is typically
driven by a 3-volt CMOS logic level signal. For
flexibility to support systems that have 5-volt
control logic drivers, the control logic input has
been designed to handle a standard 5-volt TTL
control signal. This TTL control signal input must
not exceed 5-volts or damage to the switch could
result.
Moisture Sensitivity Level
The Moisture Sensitivity Level rating for the
PE4237 in the 6-lead 3x3 DFN package is MSL1.
