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

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

Notes: 1.

CTRL accepts both CMOS and TTL voltage leads.

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.
