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.

Notes: 1. A bypass capacitor should be placed as close as possible

to the pin.

blocking capacitors.

3. The exposed pad must be soldered to the ground plane for

proper switch performance.

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.

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,

85 dB

at 5 MHz), high compression point, and an

integrated 75-ohm terminations make the PE4240

an ideal, low cost solution.
