Product Specification
PE42742
Product Description
The PE42742 is an SPDT UltraCMOS™ switch designed
for broadband applications such as CATV, DTV, Multi-
Tuner DVR (Digital Video Recorder), Set-top Box, PCTV
and Game Boxes. It meets FCC 15.115 spec of 80 dB
isolation @ 216 MHz and offers high isolation and low
insertion loss in both a powered and a unique unpowered
default state. The PE42742 covers a broad frequency
range from 5 MHz to beyond 2200 MHz with a single
positive supply and CMOS control. It provides a smaller,
cost effective, more reliable and manufacturable
alternative to mechanical relays in set-top box
applications.
The PE42742 is manufactured on Peregrine’s
UltraCMOS™ process, a patented variation of silicon-on-
insulator (SOI) technology on a sapphire substrate,
offering the performance of GaAs with the economy and
integration of conventional CMOS.

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.
1. RF pins 3, 8, and 13 must be at 0 VDC. The RF pins do not require DC
blocking capacitors for proper operation if the 0V DC requirement is met.
2. Pins 16 and 17 can be set for single pin or complementary
pin control.
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.
Moisture Sensitivity Level
The Moisture Sensitivity Level rating for the PE42742 in
the 20-lead QFN package is MSL1.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS™
devices are immune to latch-up.
Switching Frequency
The PE42742 has a maximum 25 kHz switching rate.

Figure 4. Typical Application (1 of 4)
Antenna Input
The PE42742 provides the high isolation required
by FCC part 15.115 regulation between the
television antenna and the cable plant. The
advantage of the PE42742 is that device
isolation / thru performance is maintained when
power is removed. This unique feature makes the
PE42742 ideal for set-top box and VCR
applications. The PE42742 supports signal flow
from RFC to RF1 and RF2 termination in the
unpowered state; similar to the powered state with
C1=C2 (both high or low).
