Absolute Maximum Ratings are those values listed
in the above table. Exceeding these values may
cause permanent device damage. Functional
operation should be restricted to the limits in the DC
Electrical Specifications table. Exposure to absolute
maximum ratings for extended periods may affect
device reliability.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS™
devices are immune to latch-up.

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 3.
Device Description
The PE4271 high isolation SPST CATV Switch is
designed to support CATV applications such as
premium channel service connect/disconnect switch
blocks. This function is typically performed by bulky
and expensive mechanical switches. The high
isolation characteristics (60 dB at 1 GHz, 85 dB at
5 MHz), high compression point, and an integrated
75 Ω (0.25 watt) input termination make the PE4271
an ideal, low cost solution.
The control logic input pin (CTRL) is typically driven
by a 3-volt CMOS logic level signal, and has a
threshold of 50% of VDD. For flexibility to support
systems that have 5-volt control logic drivers, the
control logic input has been designed to handle a 5-
volt logic HIGH signal. (A minimal current will be
sourced out of the VDD pin when the control logic
input voltage level exceeds VDD.)
