Notes: 1. A bypass capacitor should be placed as close as possible
Table 3. Absolute Maximum Ratings
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.

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.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS™
devices are immune to latch-up.
Device Description
The PE4240 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 (>44 dB at 1 GHz,
at 5 MHz), high compression point, and an
integrated 75-ohm terminations make the PE4240
an ideal, low cost solution.

Table 5. Control Logic Truth Table
Notes: 1. CTRL accepts both CMOS and TTL voltage leads.
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
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
