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.
Moisture Sensitivity Level
The Moisture Sensitivity Level rating for the
PE4270 in the 6-lead 3x3 DFN package is MSL1.

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.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS™
devices are immune to latch-up.
Device Description
The PE4270 high isolation SPST CATV Switch is
designed to support CATV applications such as
premise disconnect of a CATV signal path. This
function is typically performed by bulky and
expensive mechanical relays. The high isolation
characteristics, high compression point, and
integrated 75-ohm terminations make the PE4270
an ideal, cost effective and manufacturable
product of choice.
The control logic input pin (CTRL) is typically
driven by a 3-volt CMOS logic level signal, and
has a threshold of 50% of V_DD. 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 V_DD pin when the
control logic input voltage level exceeds V_DD.)
